Thank you so much, Brian for this quick rundown and educational video about crested gecko genetics. And yes, we all learned that in science, but I guess some of us have forgotten it. Either way, I love my gecko from you! I am so extremely grateful! He is so beautiful, and I can’t wait to get another one from you and breed the responsible way❣️🫶🏻☀️ I honestly could watch your videos all night long. I wish I didn’t have to get up early and needed to get to sleep.🌙
I said it before and I will say it again, this is one of the most correct and informative videos out there. I hoop you can tell us more about this topic when you find new leads after more experience with some of the morphs.
Fantastic video! You really cleared something up here and I'm glad of it because the idea that creties had 'random' genetics never made sense to me. You also inadvertently explained co-dominant traits for me; they're basically recessive but with visible hets??? Thanks!
Love love love this video. Your videos are so helpful. Would love to see updated videos with any more info you’ve learned since this video was made! You’re the best!
I'm glad I'm learning about this now since I just got into crested geckos myself. I honestly wondered how axanthic was a simple recessive trait when the common misconception has been that crestie morphs were "polymorphic"! I also breed ball pythons so I don't find that crested gecko morphs following mandelian inheritance hard to believe. Thank you for talking about this and sharing your insights!
I've been breeding reptiles (cresteds in specific) for over 10 years and I 100% agree with you in the sense that the genetics are not random and there is science behind the genetics madness. It's said very frequently in this video that people refuse to believe new information and spread false facts when I think it's much simpler than that, they simply don't know and I don't believe the reptile community to refuse to believe new facts and spread false information. I'm very happy to see a video like this to shed light on these misconceptions. One thing I would like to know more about is breeding two red cresteds together and getting brown (not black) base colours ( not really concerning any pattern traits but simply base colours) as I purchased a baby crested gecko from you, and before purchasing him I was guaranteed he would turn bright red like both its parents but 9 months later he is brown.
thank you for taking the time to make this video I've tried explaining this to no avail, I keep detailed records and I do test pairings to help me prove out and hopefully figure out non visual genetics.
I actually really enjoyed learning about the genetic side to cresteds. Also having some myths busted! I am a fairly new crested gecko owner and I have heard the spot requirements to be considered Dalmatian and super Dalmatian but your explanation made so much sense as to why that is bogus. Thanks for sharing your knowledge!!
It makes a lot of sense that there would be really complicated and varied genes that govern coloration. I think reptiles have 3 different cell types that determine color (melanocytes, xanthophores and iridiphores?). It is very encouraging that it is so complex in crested geckos. It means there is probably a lot of unexplored genetic territory yet to be unveiled.
I have always LOVED genetics!! I'm so happy to see such an interesting & informative video on crested gecko genetics!!!! I look forward to your future videos & learning more as I start my breeding projects!!!
I'm going to get a crested gecko soon and your videos are really helpful and informative so please keep making them (: Can you do a video about housing 2 geckos together?
Could the unexplained combo be that those genes are allelic? Like gravel and yellow belly, I’m ball pythons, their supers look way different but when bred together, something totally different is produced
Thanks for clearing that up!! I heard all the polymorphic being random and was completely puzzled by that. Not a lot of breeders will elaborate on that and even get it wrong (or just like spreading wrong info) so it's very confusing even for breeders who have been breeding for a few years. I am trying to keep up on all new terms and studies on genetics and new studies. I want to remain a smaller scale breeder at Seraphic Crested Geckos (in Tacoma Washington) :) Thanks for all your hard work I look forward to following you, Brian.
Fascinating topic, genetics in general, shouldn't it be possible to figure out certain recessive or dominant traits in a gecko by breeding them and catalog the results?
I'd like an explanation of other base colors perhaps. Such as yellows and oranges. From my understanding, oranges are a modified red, but I really like yellows and would like to know more about their genetics. The tiger gene for example, you don't see it on black or lavenders really, and only very rarely on reds if at all.
Thanks great video, I’ve worked with animals all my life, but when so clearly explained, I learnt so much and I also used to believe those false versions of polymorphism👍😊thank you
Outcrossing when possible is always good, but breeding related animals isn't something to be concerned about with crested geckos. Reptiles don't suffer from issues caused by this the way mammals do. Being an isolated island species crested geckos are particularly adapted for it.
I have a male pinstripe which may qualify as a quad. Typical chocolate color I'm not sure that I've ever seen anything that I could define as a purple hue. I am considering getting him a harem over a period of time. this is the first video on genetics that I have watched and am a little uncertain about the prospects of breeding with my current level of knowledge. Do you have any suggestions on either links to videos or books or anything I should be educating myself with before attempting to breed these geckos?
So im trying to breed crested geckos n i was wondering if there is a website or somewere that is good that has all the info on what trait is what in regards to dominate co dominate ect.
such a dumb question but how does inbreeding work with crested geckos? You can’t just breed the baby with the adult when “the right age and weight” ? will it lead to birth defects? Don’t breed siblings ? even if in a different batch? (:
Hello ! I am interesting in getting myself a crested gecko, and I have a question. Where I live our temperatures have been going up and down. What are the correct temperatures a crested gecko should stay at? I know they don't need a light but I am nervous for how cold it gets, should i use a ceramic heat emitter ?
I am really thankfull for this video! :) You have mentionned Red Pinstripes, but not the Pinstripe trait in itself. Is Pinstripe linebred or something genetic? I am really not an expert, but I believe Pinstripe could be a linebred trait, because there are many partial Pinstripes out there too.
How am I just finding this!? My son and I actually were discussing the genetic aspect of crested geckos - we actually had decided at the end of the school year, that we would make that his biology project for the next couple years. He is brilliant, and really has a knack for figuring this out. I do appreciate the video also, up until this point, my animal breeding was limited to sugar gliders and chinchillas. There are a few lethal genetics that come into play with chichillas - ironically it's with the white gene with them also. Do you have any suggestions as to where we should start with this? Right now, I don't have any breeders - we have a baby (looks like cream on cream dalmatian - hatch date was 5/17/18 so way too young to sex) . A patternless - red. (hatched in Dec 17) and an extreme harley - who is an adult - I need to buy a scale, but he does not look anywhere near the size of any of the adults in your videos. My guess that he is probably still considered a Juvi - he definitely isn't over 25g. If you were starting all over with this, what would be what you would want to prove first?
This is interesting, the hobby always confuse co-dominance and incomplete dominance as one. I've hear about this a lot when it comes to leopard geckos.Some people are starting to believe mack snow leopard gecko are incomplete instead of dominance. I really think they are incomplete dominance as well. Though I need to work with them to know for sure.
Is red gene incomplete dominant, or recessive? How does it react with cream? How did I get a Blade Clown from a Clown X Enchi Clown? The Blade gene is not always apparent in Enchi Clown Ball Pythons. Just some things to consider.
So, if by your example of two red/creme pinstripes creating red phantoms, (which I have done myself) and also black/creme pinstripes, (a.k.a. lavenders) and you've noted that we have yet to see black phantoms from such a pairing but it ought to be possible if not taking a long time to achieve. (unless some genetic combination we don't know about within that pairing keeps it from happening) Couldn't we claim that the axanthic is actually a black phantom ??? (my understanding of axanthic means lacking red and/or yellow pigment) Maybe your friend Catherine achieved the axanthic through such a pairing......
Axanthic and black phantoms are different. Black phantoms do exist in the charcoal morph but they are very different than Axanthic. Also, not all axanthic are black. They range from white to grey to black
Would it make sense for someone to buy plain "normal" looking crestys and start breeding them to eachother to clear recessives and make a solid clean genetically morph free bloodline?? it would take what? 6 generations or so? a great example of actual polymorphism is Buggie parakeets from Australia. The blue and the green are abundant in the wild. Therefore polymorphic. A few other slight color varients are found wild as well, but the more exotic white and pied colors you see in pet stores are not typical of wild flocks. Added bonus, Parakeets are also Gender dimorphic, the males develop a very blue nare (nose) while the females nare is brown. I can see why the hobby/industry gets the wording wrong. You explain it very well. maybe a good way to put it would be "domestic polymorphism?"
Hi, i kan help thinking of that fantome gene, could it be a co-dominant gene and the superform a patternless. ore have you tested it enough to exclude that. Jens, Denmark
Very interesting and exciting. I hope to learn as much as I can from all the legendary keepers like you that created crested gecko keeping in the US. Thank you so much for sharing your knowledge. I rescued a crested gecko (NOT to breed, just a pet) and they are a harlequin I think... very cool. I love biology and genetics, so awesome. This is quickly becoming a huge passion of mine!
