Can someone give me a generalized list of what genes are recessive and which are dominate?

The only dominant trait is normal.

LOL, okay, that list was a little too short. There is no dominance between tangerine and yellow.. etc?

no, no dominant morphs known yet. i wish there was a co-dominant morph though. especially and axanthic or aneurystic.

Tangerine and yellow is the same gene.

i don't think tangerine and yellow is the same gene. tangerine, i believe is based on the red gene. since red yellow = orange (tangerine), and the yellow is already there, when you stress the red gene it mixes the yellow and red it makes tangerine.

I really think people have a tendancy to oversimplify the genetics in leopards. Coloration in leopard is polygenic, tangerine coloration is the result of many different combinations of genes.

The whole basis behind line breeding is maximizing the amount of "tangerine" genes in one animal. That is why tangerine offspring can be so variable.

I hate trying to explain genetics in writing... it's so much easier to talk about it =)

hmm, if thats not right, then i know nothing about the technical mutations of tang leos. im not very smart, so im not going to try to understand it any way. i know enough to get by.

Lol... dont feel bad, no-one knows exactly what genetic makeup tangs have.

Good luck with your projects.

I read a lot and that's what it says in The Leopard Gecko Manual. Yellow and Tangerine are the same, just in different color "strengths." If it's not true then the book is wrong.

There is no way that tangerine and yellow are single gene traits otherwise they would be predictable all the time. You would be able to say that they are either dominant, recessive, codominant, ect but since it doesn't work that way it has to be a whole mess of genes so it is unlikely that the genes can be understood properly unless they can be isolated. Smae with abberant genes.

Grrr

Red and yellow do both come from the same gene however high yellow and tangerine have little to do with this gene. They are both polygenetic but that is because they deal with more color the only thing the red/yellow gene affects is will there be red and yellow at all. Many species of snakes have Axanthic and Aneurythristic (sp?) morphs. Axanthic is the lack of yellow and Aneurythristic is the lack of red. However since red and yellow both come from the same gene all Axanthic snakes are also Aneurythristic and all Aneurythristic snakes are also Axanthic.

Tangerine and yellow are not on the same gene... infact there is no "one" gene that controls tangerine or yellow, as they are polygenic traits.

Many different gene combinations determine the "background" color of a leopard gecko... that is why tangerine is a line bred trait.

When you breed two tangs together you hope mom contributes tangerine genes that dad is lacking and vice versa; thus producing offspring that are even more tangerine than the parents.

recessive:
all forms of albino
blizzard
patternless
there may, or may not be a recessive form of striped, i think there is.

that list feels short, but i can't think of anything else right now.

And Tremper claims his Giants are a recessive gene

ahh, yes, thats it. it's hard to believe its a recessive gene. as josh, i think it was josh, pointed out, if it was recessive, how can the giants vary in size so much, and how can they be getting bigger?

I agree it's hard to believe, you'll notice my phrasing "Tremper Claims"...I personally would not buy a "het" for Giant. But Tremper says it's true, and I certainly won't call him a liar just because it's hard to believe. Of course, people can be mistaken on both sides...people started claiming jungle was recessive years ago, and I think general opinion is finally starting to come to that poiint of view.

I completely agree with Ross. Listen, not even "tangerines" can be categorized under just one type of gene. When breeding this lizards, and depending upong the whole "Genetic Tree", you will get an enormous variety of looking tangerines, for example. If some dont belive, check this out...it has happened to me and probabbly to most breeders. 2 eggs, coming from the same parents, coming from the same set of that season, and even coming from the same clutch...and when they are born, they end up being two tangerine. When they grow, they can look completely different. This is just to convice you about the variety of this genes. Also, then, next seaon, you take this tangerine and you breed it to another male, lol, completely different looking tangs. So, summarizing. tangs and hy are not the same gene, although they may look alike "sometimes". When reading carefully the Leopard Gecko Manual, that will not be the only thing that will be confusing for you. or even miss written.

LOL! Isn't that the truth!! Try the section on incubation temperatures...Ay yi yi!! Can they possibly word it any more confusing?? LOL!
