Genetics help please

[RepGurl]

So I know that some morphs are co-dominate (like mack snow, and giant), but the only morph I have read about being true dominate is enigma, is everything else a recessive morph? Do leopard geckos really have that many alleles?

 

[Halley]

There are recessive, and polygenetic traits (Gem Snow is also believed to be dominate)

Here is a good link:

Leopard gecko genetics is in its infancy. Lab mice have been studied for nearly a century, and it it takes a book two inches thick to list their mutants with a brief description. Expect more dominant, more codominant, and more recessive mutants to show up in leopard geckos with time.

Besides this, there are some traits that are polygenetic, but behave as a simple recessive or co-dominant trait. As PaulH sais, not everything is clear in Leopard gecko country....

I believe that most traits are polygenetic--but since they behave like recessives, it's just easier to call them recessives. IMO, the giant trait is also polygenetic, not co-dom, but it does behave similar to a codom. This is an emerging science, and it is growing exponentially...we're going to have to rewrite the books every season

How does a polygenetic trait work?

 

[Halley]

Well that question is a difficult one to answer, as like, Yuri, said before some polygenetic traits act simple recessive or co-dominate. However polygenetic means many genes (not to scientific but it gets the point across quite well), the wording I give you will be a little odd, as I cannot find a good way to explain this but I will try and do it by example.

Okay, lets start with this, you find the best tang out there, and then the second best tang out there and you breed them together. Theatrically you should get offspring that are in the same “league” as the parents. However let’s say you take a mediocre tang, and breed it to an equal, these offspring as well will be in the same “league” as the parents. However the offspring from the two best tangs in the world are going to be better than the tang created by the mediocre pairing. Like major league, and D5 College ball. However lets say you take the best tang in the world, and breed it to one of the mediocre tang, the offspring wouldn’t be in the major leagues, but most of the offspring will probably be in D2, with some in D1, and other ones in D3.

Don’t know how much sense that made, but really polygenetic traits, anybody can understand, without any real genetic knowledge.
