Hi, everyone! Thank you for all the kind words! ‼️Corrections/More Fun Details - The Sims 3 is still able to pass down colored hair, regardless if it's genetic or dyed (not sure why my first try in the video, the child doesn't have colored hair) (thank you @maveurent4445) - Sims 3 has chances to inherit grandparents' feature (for me, it's not recessive/Mendelian genetics like Sims 2, but more like, there's x% chance, but it is entirely possible, it's not 50/50 only from parents as I said in the video, sorry! it is ~54% parents, ~36% grandparents, ~10% mutations) (thank you @disaster4550 and @wikicatyt) [I made a short about it: ru-vid.comPZX8bOxDeTw] - About Sims 2's CC eyes, Sims' eye colors isn't always dominant, but it depends on what the CC is overrode from, so it is possible for CC eyes to be recessive if the creator intend to do so! (thank you, @lumare) It's so fun reading your comments, I'll be updating here if more comes up!
sims 4 sims also can inherit crazy coloured hair, just not as a child because those colours don’t exist as child presets, so the game picks a random one until they become teens
@dzastin0713 Unfortunately there are no grandparent genes in the Sims 4. If you are seeing them in your games it is most likely just a coincidence. The whole genetic system in the Sims 4 is quite broken.
Tbh human genetics are so complex that maybe the Sims 3 is the most realistic in this case. The dominant/recessive traits are approximately true for eye colour and ear shape irl, but even then there are so many variations that don’t fit neatly in. That being said, I would like to see better skin colour genetics - generally speaking, a child can end up darker/lighter than either of their parents, so it would be nice to see such mechanics in game as well.
@@bobi7152 In Sims 3 I've had Claire Ursine's daughter (red-haired & green eyes) marry a sim super pale with platinum blonde hair and pale yellowish eyes, they had a daughter that mostly looked like her mother red-haired kinda blonde with green eyes, then she married an imaginary-friend (in my game I always make them match their clothes to be colored like their dolls versions, so they are basically a berry sim) he turned out to have orange skin/ and orange/blonde hair with a really bright light blue eyes, and for my surprise their baby came with his grand-father skin tone, hair color and his mother's eyes. Luckily I was doing a random challenge and I have pics on my tumblr, it was a surprise, I wasn't expecting at all for him to turn out like his grandfather and I find it so fascinating! Before playing this challenge I would always play between families till something goes wrong with my pcs, so I've never played a save longer enough to testify something like this. Grandparents (mother's parents) : ury1.com/JxyzF & ury1.com/07EXL Mother: ury1.com/QBkBv & Father: l1nq.com/MZDep Son (with grandfather genetics): l1nq.com/an4l9 & ury1.com/Uu9pB
Every time I revisit Sims 2 content I still dream of a sims game with Sims 2 mechanics and Sims 3 open world deal. Preferably can import and interpret CAD and DWG files. haha
Omg I just thought so and I also agree about the sims 4 cas system. I just love the attention to detail in sims 2 and also the chaos it has to make interesting stories!
@@redbamboozoneI love the Sims 4 build and buy, every time I go back to the Sims 3 I have to remind myself that I can't just pick up and move a room 😂😭
Also want to mention that CC isn't ALWAYS dominant. Most people who make custom skintones or eyes often 'geneticize' them and place their cc in similar values as the game uses, so it rolls the same as base game eyes or skins. But if they're not geneticized, they're always a dominant trait.
This is one of the reason why I'm still playing the Sims 2. The genetic system is incredible and you can really see both parents in every children's face. There's also the fact that imo, the Sims in 2 have the most easily recognizable features. In 3 and 4, the sims have rounder, softer features that makes them look a lot less unique from one another. When a sim has a child in 4, I honestly can't tell if they actually resemble their parents or not, due to everyone pretty much looking same-y.
I actually think Sims 3 isn't much behind when it comes to the genetic aspect. My sim had a baby girl (named Olivia) with Connor Frio, and when she grew up to a child, I could definitely see that she ressembled her dad more, waaay more, and then she developed her features more as a teenager and started looking like her mother, and now as an young adult, she looks a lot like her mother, but with Connor's lips and haircolor. Olivia now is expecting a baby with her imaginary friend turned lover and I can't wait to see how genetics will play out
This is why I never understood why anyone would get the equal genetics mod. TS2 genetics are just so cool! I’ve heard players claim that all their sims will end up with black/brown hair - but this isn’t true because TS2 have reciessives! Sure, most sims will but youknow - thats just what real life is like as well? Most people have dark hair!
It is cool in theory but while actually playing, it’s annoying because the recessive genes are extremely rare to pass, let alone from grand or grand-grandparents. Even in real life, I see blond hair and light eyes pass all the time. I don’t really think this is how this statistics works, so equal genetics mod seems more realistic to me.
Eh, I can see why people would want it. Sometimes the recessive genes just don’t pop up, and they might wanna see some blonde, redheads, grey/blue/green eyes pop up in their game more often.
Well, plus cant you just like, edit their hair color and say it was dyed or something?? Though, perhaps they could also just make recessive genes more likely. That would fix most issues.
Sure the first born in-game gen becomes predominantly black/brown, but it starts to fix itself in the next gen when all the black/brown haired sims with recessives start breeding with each other. You can level it out even more by giving cas made sims recessives genes of their own so there isn't any heterogynous dark-haired/eyed sims to begin with. Same with pre-mades using SimPe.
My friend, your English is what I would essentially consider to be fluent. This is some real complicated stuff you’re talking about and doing so flawlessly. Your pronunciation is also 99% perfect. When it’s not perfect it’s still entirely understandable! Great vid
as a CC creator from the sims 2 days, if you made eye colour overrides, they didn't automatically go dominant - they took on the dominance/recessiveness traits of whichever default you overrode.
Made sense, thank you! I edited my pinned comment to clear it up. I was actually hoping to come accross Sims 2 CC creators in the comment section, nice to see you here😊
@@weisya cheers! I was Kiki, I made the Phasmatic set of skintones and eyes and a bunch of Maxis Match clothing - watching your video made me miss sims 2 so much!
Something that really annoys me about the Sims 4 is that if you customize a sim's skintone swatch in CAS using the slider, it totally screws with the genetics. Also it can look so bad if a child inherits one parent's color hue and the other parent's value, it can make the kids look absolutely nothing like their parents and unearth weird skintone swatches that look purple or ghostly.
I love the genetics in sims 2, this is why I have too many sims as well. I like getting that extra surprise 3 generations in of a recessive great great great grandparent. I do wish the twins could be identical, but that is just one small issue for me.
Boy/Girl twins are fraternal and have as much chance of looking alike as any two siblings. There’s also same sex twins who do not look alike and are fraternal and not identical. Identical twins are the rarest twin set actually IRL.
Rather it is just the genetics of the grandparents, but blond or red hair is not a recessive gene by default, and there is also a random mutation where children are born with swamp or blond hair
after getting halfway through, i can proudly say that sim science is definitely my cup of tea 😌 i was never into science as a kid, but biology and genetics were always interesting. i could sit and listen to someone pick apart this game for hours.
I think the reason you can’t find the 2 skintone genes received from the parents is because in some cases, like Olive Specter (I think) the game would get confused with incomplete data and the child would be born with some weird skintone.
I wish more sims 2 characters did breed out the weird challenges also from my experience, with the exception of default replacements, CC always overrides genes.
Oh man, it’s like this video was made for me. I love genetics and The Sims 2 so much! The genetics system is just another example of how much love and hard work was put into TS2. It’s the little things, you know? One thing about CC genetics, though, is that while some creators will give their CC custom genetic values, others will create default replacement CC which maintains the original genetic values. Wonderful video!
It was very interesting to watch ! I've been playing sims 3 much more than sims 2, and I've always been fascinated by the genetics of the game ! Whenever I have a new kid, I try to compare them to their parents to guess which trait has been inherited from whom. However, I think sims 3 also has recessive genes ; I very specifically remember having a girl being a literal clone of her grandma, even though the mom looked more like the grandpa !
That's so cool! I tried using Sims 4 to generate children for a character design, but I got frustrated at how random it was. I'm only old enough to have started with Sims 3 but it's cool how Sims 2 had these mechanics
Something I really hated about the sims 3 at least was how my genes transferred. Specifically with eyes I remember them being really fucked up bc two characters with completely different eyes had mixed.
I'm a new subscriber specifically because of this video! Something that has always surprised me is that the Sims 4 was not coded to rely on in game genetics equal to or moreso than in prior Sims games. Granted, the Sims genome would be far more simple than a real genome, but still, why not just use a basic version of what exists in the real world. I haven't thought about the lack of quality genetics in the Sims 4 in quite some time so I don't recall if anyone has ever asked the devs etc if it was attempted or not. I'll have to look into it. Here's hoping they utilize genetics better in the Sims 5!
Oh, coming back just to add one thing: If you want to really thoroughly examine a Sim's face for which traits they've inherited, you can export them with SimPE, clean the saved sims up in Body Shop, then go into CAS and compare the templates there by selecting the kid's face, changing skintone/gender to match the parent you're comparing them to, and then selecting the parent's face and seeing how much stays the same. I've done this a few times to see if Sims who looked like clones of one parent actually were.
What a great video! Your editing skills are amazing! One thing I will say about the genetics system is that I've had moments of "blending," which you basically described in this video with skin color. I've seen it with hair color as well (not sure about eye color, I don't often pay attention to it lol). For example, I had a Sim with brown hair who had kids with someone with blond hair (neither were born in-game). They had 4 kids: one was a brunette, 2 had blonde hair, and 1 had red hair. The red-haired child was sort of a blend between the two. I also had this happen with a Sim with black hair who had a child with a blonde Sim, and one of their kids had brown hair. So, on top of the dominant/recessive genes, an entirely new possibility could occur.
I like how the Sims 2 made realistic genetics but the amount of playable sims in neighborhoods is so low compared to real life that after some generations everyone has brown hair and brown eyes. That's why I use the mod that makes every color 'dominant'.
Wow. You put a LOT of work into this video! Very impressive and I’m so happy to see someone else nerd out over genetics ❤ Edit: You’ve gained another subscriber 😊
Another fun thing to know is that skins cam show uo differently (use different set of textures) per differently expressed hair color. And also that when making your cc you can choose where in the range skin color and eye colors would be. With these two i made a skin pack that shows freckles more for red and blonde hair and less for brown or black hair. I planned to make a genetic body hair versions too.
this is so cool! ive played all 3 games and have always noticed sims 2 always killed it with the genetics way more than 3 or 4, super dope that you made this video! thanks for confirming my suspicions! also, you are not hard to understand at all!!! you are very clear and precise with your english people are just dense!!
Glad to see this because I thought I was going crazy. I haven’t played TS3 in years, but I swore I remembered having kids inherit grandparent hair and eye colors.
Till this day I still agree! Sims 2 genetics with dominant and recessive trait with a depth with real life biology. It's giving Biology 101 by just playing the game. Sims 4 could never hahah.
Sims 2 is the game with most realistic genetic system ever! I'm really want to learn how to program games and simulations in Godot and want to find a tutorial about implementing such realistic genetic mechanics such as sprite appearance and stats. I'm not really a programmer, just an visual artist by the way.
This video is so informative! I personally love both 2 and 3's genetics. I really hope they expand on 2's in 5 but also have the option to turn it off and just go 50/50. I can see myself using more realistic for legacy families / saves and 50/50 for silly challenges and plain ol' fun.
Sims 2 genetics are awesome! one of my families, the husband has black hair, as did his parents and all 4 grandparents. His wife also has black hair. as her father. her mother is a blonde though. The couple's firstborn? a redhead! Turns out the fathers great grandmother was a redhead. the gene for red managed to survive as a repressive gene for 4 generation's in his lineage!
If my sim inherited a cosmetic trait, I be pissed and it would mess with my suspension of disbelief. Very intelligent video. Genetics was a favorite in school. I enjoy those genetic unicorns and feel that recessive genes ensure physical diversity among sims. I never understood that complaint about a town full of brunettes. Make sure the sims you make aren't brunettes🤷🏾♀️🤷🏽♀️🤷🏼♀️🤷♀️
TIL that features in my favourite game, TS2, are dominant/non-dominant. Is that why sometimes my couples seem to have clone babies even when I’ve definitely rolled the pacifier for randomness and they have different personalities- it’s just that one of the parent’s features are more dominant? So cool! I’m diving into SimPE tonight to find out more about this (especially for one of my BACC families where all three kids are basically identical but one’s Leo, one’s Libra and one’s Aries!)
I'd for the genes to not be recessive or dominant, however I would like Sims born in game to have the possibility of Heterozygous genes. That way I could have a grandmother with red hair and at some point down the line have a great grandchild with red hair because the grandmother's gene was passed down but lost the 50/50 chance of being shown. I also love the idea that the game remembers the parents true hair colour.
HOLY COW! your videos are so incredibly impressive. there's so much detail and it's all so easily digestible, it really makes me love the sims 2 even more but also long to learn more about it! you rock!!!
I just recently came across your content and subbed, holy hell it's so good omg ????? I loved watching this in-depth analysis of how genetics work in ts2, I haven't really seen anyone talk about it! It's extremely fascinating and a very very well made vid :DD
From my experience, the sims4 still has the "carrying genes from generations" ability. I remember my black haired sim got with another black haired sim and they had blonde twins. It surprised me because the grandmother of the twins has blonde hair. The other black haired sim was made in cas, so it couldnt have been from her. They got their blonde from their father's side
Awesome video! I’m a TS2 player and I do use some mods to alter how the genetics work (most importantly the equal genetics mod), but one feature that remains and I love is inheriting the recessive genes from prior generations. I have one family where the first gen was a black haired and a blonde Sim, and all their kids had black hair. But in the third generation I got a blonde kid again (even though her parents were black haired and a CAS “born” brunette). It’s always so exciting! 😂
It's actually quite nice to see someone talk about the subject of genetics that runs through the sims 2, being fascinatingly realistic. However... if Zach and Amelia were the first in their family, what would be the probability (putting them a number) that their children would have red and black hair? (I know it's silly to ask despite the explanation you gave in the video, but I speak Spanish and the subtitles of the video were not activated)
Amazing video! The quality of your videos is amazing! After watching one of your videos I was hooked and I watched more, I even subscribed! I hope you continue making videos because I really think you have the talent for it!
i've stumbled across your channel and i absolutely LOVE it. the editing is amazing and you go into such great detail. it's bringing back so much nostalgia for the sims 2 i forgot i had
The dominant/recessive thing in TS2 always made the neighbours filled with only brunette/brown eyed sims over a couple of generations, so I'm not complaining this one aspect has changed.
This is really amazing that they went through all that for the mechanics of biology and genes. It's like in my family: mom's got green eyes, dad's got grey/blue eyes, my brother's got grey/blue eyes.... and I have boring brown eyes (from the grandparents). How unfair!
Love the video! The genetics system is one of the reasons I still play Sims 2 and prefer it over the later games. I even made a mod that assigns separate genetic levels to each hair and eye color so that I can more accurately Punnett square my Sims' offspring. (In my mod, the hair colors from most dominant to most recessive are black > brown > red > blond and the eye colors are brown > green > dark blue > light blue > gray. So if you'd been playing with my mod, Gabe and Gabby would be redheads like their mom, with a recessive blond allele each!) Since you mentioned SimPE, I do think it would be good to mention that you can use SimPE to modify genetics. I like to do this in my own games often, usually to see more variety in the children of townies and Uni Sims. The method I use is to generate a random number between 1 and 4 for hair and a random number between 1 and 5 for eyes, with lower numbers corresponding to more dominant traits (according to my mod). If the number I roll is higher than the number assigned to the Sim's expressed trait, I give them a recessive allele for the trait that corresponds to that number. So if I take, for example, Tiffany Sampson from Sim State University (homozygous for brown hair and dark blue eyes) and roll a 4 for hair and a 2 for eyes, she gets a recessive allele for blond hair, but remains homozygous for dark blue eyes. Skin tone in Sims 2 is interesting. There's a range of potential values from 0.01 to an unknown upper limit that you can geneticize your skins to. Base game pale is 0.1, base game tan is 0.3, base game medium is 0.6, and base game dark is 0.9. If you added a skin with a value of 0.2, a sim with base game pale skin and a sim with base game tan skin could have a child with that custom skin tone. If you added a skin with a value of 0.95, then a Sim with that skin tone and a Sim with base game medium skin could have a child with base game dark skin.
nahhhh the cursed ass looking sims were wild 😭💀 great video though, very informative and interesting, but those crazy looking sims caught me off guard. The alien sims look so cute
That's crazy, the video shows in-game footage that I did, but then I just tried it again to make sure and it turns out.. they actually can? Thanks for that
Great video! One of my pet peeves when it comes to Sims 2 genetics is that there is no hair colour range. Two sims with only black and/or blond hair genes will never have a child expressing a mix between the parents' hair colours. It will either be black or blond, never brown.
Something must have been wrong with my sims 2. I struggled to keep red hair away. Red hair tried to dominate along with a cc I wish I didn't get. It was a skin tone that was way too red. That dominated all townies with red skin and red hair. It was unrealistic. I like the idea of the dominant and recessive.
They totally can, I’ve had it happen multiple times in my game. When she claimed the ts2 was the only game with recessive genes I immediately went to the comments to see if anyone else noticed that was incorrect
Yeah, I've seen it being discussed in forums, but I couldn't find any certainty for the exact mechanism (except mutations chances), and I didn't see it as recessive because I'm not sure if there's any dominant traits that will undeniably get expressed when paired with its recessive trait, but I'm aware of this, if anyone find some sources on how it works, I'll make sure to cover it👍
I found your video very interesting. I subscribed. I have alien in my family where the blue skin tone was active after 4 generations though somewhat long lighter shades of blue.
It's really disappointing that my sims and their pets in Sims 4 looks almost identical to either one of their parents with extremely low variation or mutation rates between the offsprings. Really which the Sims 5 would improve that to something similar to Sims 2 and 3.
I'd love to have a genetics mod for Sims 3, though i hope weird colors like pink hair or purple skin would still be possible to be inherited even if they are recessive
I love that contrast between lively, lovely and happy Sims 2 characters and Sims 3 Sims 4 completely ugly soulless bots. Especially Sims 4 :'D You got me! I'm subscribed :D
I would pay 60 dollars no complaints for a sims 2 remaster (adding open world from sims 3, and maybe the building tools and CAS dragging + multitasking abilities of sims 4 to really knock it out of the park since it's able but NO OTHER CHANGES because everything else in the sims 2 is perfect as is tbh)
I have installed the equal genetics mod and after dozents of babies I have now a family who has the following set up Mary has blonde hair Gerald has brown hair Their son Simon has brown hair Abbigal has black hair Charlie has red hair Their daughter Chinsey has red hair So Simon and Chinsey had two sons The first Jacob got black hair from his grandmonther on his mothers side The second Caleb got blinde hair from his grandmother on his fathers side. It was amazing to see genetics being passed down as recessive. I don't even know what color the boys carry now as recessive one. Could be brown or red. XD
