Genetics

Dedalus Feb 01, 2004 03:28 PM

Does anyone know of an online genetics calculator or something?

You all remember punnets squares from high school Bio. Is there anything like that online for figuring out bloodlines.

I have a high yellow, a leucistic, and a norm. in one breeding group (the second is all hypo tangs or carrot tails). If I cross the leucistic with the high yellow what kind of offspring could I expect? (Im assuming norms, high yel, and het leu) Is there a chance for pure leu offspring in this pairing or will I have to breed back?

www.geckogenetics.com is a really good one.

you'd get high yellows and normals all het for leusistic with that crossing. There is a website to get numbers from...but its not hard with punnet squares if you know anything about the genetics behind the traits. I think the website is www.geckogenetics.com

I just hit the site up and it's coming up genotype and phenotype 100% patternless.

StinaUIUC Feb 01, 2004 04:07 PM

het patternless or patternless?...there is no way possible to breed a patternless with a non-patternless and get all patternless babies...if the non-patternless is het for patternless you would get a quarter of the babies to be patternless

I like this site for genetic caculations. The first thing to find out is how each of the traits are passed on. Are they line bred, recessive, dominant, ect. In your examples the patternless is recessive the normal or WT is dominant. The high yellow and hypos are line bred. So then you can go and find out how they will be passed on. In your case with the patternless you would get 100% het patternless, since there is a high yellow in the mix some of the offspring could be high yellow as well. Hope this helps

Thanks that explained it a bit better. I'm having trouble remembering grade 11 Biology :P.

Basically I'm gonna get norm's or high yellows that are all 100% het patternless. If I bred those 100% het offspring I'd have a something like 1 in 4 chance of patternless. But I'd also have 100% inbred geckos and no one wants that.

a lot of people actually breed offspring together...the only problem with inbreeding is that it brings out genetic problems more quickly than other breeding programs. You can actually use it as a way to identify problems in a line and breed them out.

Hrmm... Is there a large chance of birth defects or immuno syndromes like in mammals? I know when my friend bred his day geckos (sis and bro) he ended up with a gecko that has 5 legs.

StinaUIUC Feb 01, 2004 07:45 PM

I'm not sure what the actual chances are...and your friends day gecko may just have been something that happened in the egg...its probably not a genetic defect. There's really only a chance of genetic defects if there is a problem hiding somewhere in the genetics...usually there are problems hiding somewhere, but those problems generally don't show up with one generation of inbreeding. It usually takes several to many generations (unless there is a simple recessive problem...) for inbreeding health issues to show up. If you breed one generation of siblings together I think you'd be ok, then maybe buy another tang albino male to breed to your female offspring to bring in some new genetics.

I figured it was just a freak gecko but he insisted it was inbreeding... but whatever.

The plan was to get some patternless breeders and try crossing them with my tang's or my buddy's albinos to see what happens.

StinaUIUC Feb 01, 2004 08:46 PM

I don't know how he could be sure it was inbreeding just by looking at it...lol Someone on here recently got a 5 legged leo from one of the breeders, extra legs and things happen...its almost always something that happened early on in the egg.
