explain gtp genetics to a ball python person

can someone explain how gtp genetics work, or post a sticky or a link to a website that can? as a bp breeder i am mighty confused, i struck up a conversation with a gtp breeder and he got me interested and threw me for a loop when he told me gtp genetics don't act like bp genes, recessive, codom, and dominant and that he didn't want to get into it because it was a lot to explain. i've been in his position many times with bp genetics noobs, so i was hoping for some help here.

genetics is genetics no matter what the species. co-dom, dom, and recessive pass on the same no matter what the species. I dont breed gtps but the only thing I can think of is the localities being a little different looking or maybe the traits that are desirable in them are polygenetic.

i can't seem to find any internet sources explaining how they work, only book recommendations. and this guy said he was breeding, essentially, a blue to a blue and that he didn't know if any of the babies would be blue, and that there wouldn't be any "super" blues. And i asked him if blue was recessive, codominant, or dominant and he said that isn't how it works in gtps.

They are nothing like bp. if you breed blue to blue you can get green. they aren't inheritable by simple Mendelian genetics.

And not all genetics is simple codom, dom, and recessive. There are a number of traits that don't act like this.

THIS ^^^^ is what i was trying to ask about. are gtp genes just completely random or is there some order to them, perhaps a different method of organization (not Mendelian) ?

A polygene, multiple factor, multiple gene inheritance, or quantitative gene is a group of non-allelic genes that together influence a phenotypic trait.

Thanks for clearing that up. Now where did I put my dictionary..

What he means is that it takes multiple genes to produce a certain look to a GTP. The problem is that there are different ways of doing this, so a blue to a blue might not produce a blue, since they have different genes that produced that blue color. The genes individually wont produce blue, but they do together. I think if you have two blue GTP's from the same breeding, that they would have a better chance at producing blue GTP's, since its the same gene combination.

LMAO oh this sooooo made my night. :D

wow this is really intriguing. non-allelic is the key phrase for me here.
