I am considering breeding leopard geckos. I have been considering buying some geckos from K&N Reptiles, ive met those folks a few time and them seem good. Thing is, i dont know anything about the genetics and cant find a source for info. can anyone point me in the right direction??? if anyone knows off the top of their head, is tangering a genetic morph? dom. or recesive? thats what i would like to breed.

thanks.

Neither! It's actually line bred.

PS. K&N is wonderful to work with! I have purchased a few geckos from them in the past.

Some lines are genetic but some aren't.

True.... sorry for my inaccuracy... I was thinking about the tangerines that I personally own... forgot about the others. I guess I'll have to be stoned to death...

what about lavender?? is that line bred too?

>>what about lavender?? is that line bred too?

Yes, it would be a line bred trait similiar to pastel or some tangerine

what does line bred mean? i only know a little about genetics.
Ok so u take an animal homogenious for the dominant trait, and a animal expressing the resessive trait (also hom). You would create animals that only express the dom trait, but all would be hetero, meaning one dom allel, and one resessive allel. right?
then u take two of the hets and mate them, ending up with 25% expressing the resessive, 50% het expressing the dom trait, and 25% hom for the dom trait. So what is a double het? and unless you are breeding two animals that are deffinatly het you will produce nothing more then more hets or homogeneou dom.
Are all traits but normal, resessive?
Since i'm still learning, please correct me where i'm wrong, and fill in any blanks.

correct. you would have 100% hets

>>then u take two of the hets and mate them, ending up with 25% expressing the resessive, 50% het expressing the dom trait, and 25% hom for the dom trait. So what is a double het?

Double het means that it is het for more than one trait. Ex: double het for patternless albino would mean that it looks normal, but is het for patternless and het for albino.

technically, to 'line breed' means to inbreed. however, when most people say 'line breed,' they mean 'selective breeding,' which just means to breed based on looks, which may or may not be inbreeding.

though all color phenotypes are controlled by genetics (aside from the possibility of pigment retention from diet, which i don't know about in leopard geckos), i've never heard of being 'tangerine' as controlled by a single dominant/recessive gene. who is claiming to have geckos where that is the case?

color intensity (like being 'tangerine') isn't a simple recessive/dominant genetic trait. it comes from selective breeding.
