I'm surprised that more Intro Genetics videos don't talk about pedigrees! Including mine, lol... We're modifying & using them very differently here than how scientists do, but that's okay. It's time to Frankenstein our way to making genetically-realistic fictional characters!
Also: I completely forgot to put them in this video, but MessyBeast has examples of REAL pedigrees that utilize little doodles of different traits instead of squares/circles. I highly recommend checking them out for inspiration :3

7:06 if anyone wants to know more detailed Tortoiseshell (and Calico) are actually fully effected/expressing both Xy males are only going off of one X chromosome so it expresses whatever is on that one X (which is from xx parent) Xx and xxy, females and males have multiple X’s but each individual cell only wants to only code for one so it tries to inactivate the other ones Aka in individual cells it tries to make sure there’s at least one functional x and if there’s any extra it tries to deactivate the rest This is called x chromosome inactivation, which is decided at random and happens in very very early development. So when you look at the different color banding you can see the physical representation of which x is activated where. Which is pretty cool.

God. I just had my AP bio test a few weeks ago. It was with great joy that I threw out every single scrap of paper from that class turned my brain off for vacation mode but this video is giving me war flashbacks. I love paleobiology and taxonomy but I never wanna see a god forsaken pedigree, chi squared test, or Punnett square EVER AGAIN. (I would totally get a phylogenetic tree tattooed on me tho lmao). I hope Gregor Mendel is having fun with Satan because he must be a demon after the hell he put me through! So anyway, I'm starting a bachelors in bio in about a 2 months :) Thanks for the Great video!

Good video! Thanks for distinguishing pedigrees from other family trees. I work on a journal that publishes, among other related articles, papers about genetic diseases, and every now and then a pedigree appears in a figure. My job when it comes to these figures is less about the science and more about "did they label everything properly and is everything legible," but this way I can refer to the figures more accurately. :) "badly impersonates a waterfall" I love your captions!

@positronixartandlife4545 Месяц назад

Oh I neededed this! I have a vast Lion King family tree that I've been keeping data on (it's NINE GENERATIONS and I've only done the main/royal branch) and there's three sets of genes in play - mane colour, fur colour, and eye colour. I'd been rolling genes randomly from what's available with a bit of manual tweaking if I want specific genes passing down but this will make things so much easier!

@Sarah_Bragg Месяц назад

I learned about pedigrees because my genetics teacher finished up faster than they should’ve and needed something to fill in some more days, and I had kinda forgotten that not everyone had that, so glad you’re sharing this knowledge! Even when doing genetically accurate stuff, I barely make punnet squares because they aren’t applicable, forgot everyone else didn’t know about pedigrees. 😅

@positronixartandlife4545 Месяц назад

Coming back here to add another comment: I have found a program that can kinda somewhat let you track genes so you can do all the above (somewhat) easier! It's called the Pedigree Chart Designer by CeGaT, completely *free*, licensed for personal, medical, and commercial use and available on Windows/Mac/Linux The downside is that the maximum number of phenotypes per chart is a maximum of 8 (good thing the number of eye colours I track is 8) and most likely you'll need to have separate charts for eyes/fur colour etc. BUT it's free, has a drag and drop interface and while you can't change the colours of the phenotypes it has done a lot of good work for me and ensures that I can have a huge mess of family trees/genetics (as I am tracking FIVE kingdoms and making sure no one is too closely related) I don't know how it'd work with many, MANY different entries but it should be a handy alternative to a paper-based system or creating one in an art program :)

You should try this with horse colour genetics :P It gets complicated real fast! The only one I know on top of my head is that a Chestnut (2 red genes) and a Cream horse (2 cream genes) will always result in a Palomino, as Palominos require one cream gene and one chestnut gene to occur.

I breed plants and I’m loving your videos! I am curious how you would handle a pedigree where a single plant could be the mother, father, or if self-fertilized, both at the same time.

@littlehungrywarrior Месяц назад

I wish I knew, sorry! I'm notoriously bad w/plant biology (esp their ploidy...oh man.) but I would think drawing out a pedigree means figuring out the relationships first, and then drawing them out, so.....whatever method you use to figure that out, then the tree? unless there's some gene that's understood well enough that you could be like..."well, we know it's dominant, but this plant doesnt have it, so it cant have self-fertilized."

@carimeslockdownedtree2654 Месяц назад

And this is exactly why the brother in my family isn't colorblind despite the two sisters somehow BEING colorblind. It's unlikely, but hey, he got mom and dad's non-colorblind genes, while both sisters got BOTH colorblind genes. For males, only one colorblind gene needs to be passed on for the person to be it (either X OR Y), but for females, it has to come from _both_ sides (BOTH X AND Y). So yeah, it's improbable, but it happens. Pedigree showing our colorblindness, where the tracked trait is recessive (white): P1: 🔲 (A/a), 🔘 (A/a) F1: ⬛ (A/A), ⚪ (a/a), ⚪ (a/a) Dad only has one and is XY, so he's colorblind. Mom only has one and is XX, so she isn't. Brother has none, so he isn't, while sisters have both so they are. Didnt know of this tree, but it's fun to see how easily you can figure out the way genes got passed down. Nice video! Taught me something very interesting. Unsure how i may use it in the future, but it's good to know either way!

@wbenga Месяц назад

Just one little correction. Colorblindness (at least red/green) in humans typically is sex-linked. In other words, it works exactly like orange does in cats xD

the red LOCUS is sex-linked, so both "red" and "not red" are sex-linked. the genes that control what color "not red" is instead of red are not sex-linked :)

@littlehungrywarrior Месяц назад

@tisvana18 Месяц назад

I didn’t know people did punnet squares for characters at all, that seems so strange to me lol. Like, if I have characters who have a kid that looks dramatically different from them hair/eye/even skin color wise, I just need to make sure there’s someone with those traits somewhere up the family line. Especially with eye color, eye color genetics irl are funky. Skin and hair color are more standard, but you still get quirks from time to time (blonde hair red beard, red hair two blonde parents, platinum blonde from two dark haired parents, etc. These make sense when you look at a punnet square obviously, but my point is that it’s more like eye color where you can’t easily tell what you’ll get from looking at mom and dad) Like the only thing that really doesn’t tend to vary from punnet squares is blood type, and even then there are still the occasional surprise unexpected blood type stories where it’s “impossible” yet both parents are their parents.

@littlehungrywarrior Месяц назад

@@tisvana18 Yeah, with human characters doing punnett squares is mostly pointless since we don't exactly have like. markings lol. most of our defining features are just gradient traits w/some known key recessives. it makes more sense w/domestic animal characters. I've never heard of anything like that happening with bloodtype tho. if you have a case study please do link me in tumblr! I'd be interested to read it (or them if multiple) :3
