I know that the whitesided gene is a recessive trait, and must be contributed by both parents in order to produce a visual specimen, my question... what other genes are recessive, and what genes would be co-dom? The co-dom would only have to be present in 1 parent in order to be visual right? Also when an animal expresses multiple traits, like a patternless whitesided hybino, are the expressions usually recessive, co-dom, or does it matter?

Hi...none of the currently accepted genetic mutations in P.c. sayi are non- recessive. When they are combined to produce "multi-morphs",or combinant homozygous individuals,all of the respective traits involved are still recessive,in other words they never change their transmissive nature.

I agree, no co-dom genes in Bull Morphs. All are recessive, accept Red and Yellows. Reds and Yellows are a line bred traits. The yellow gene is more reliable then the Red. By secound generation the Yellows, are Yellow. While with the Red it still a guessing game.

OK, so in order to produce a visual anything, both parents have to contribute the same trait...right??

Yep that is correct.

An unrelated pair of bulls showing the recessive gene for patternless; I expect all their offspring will show the visible trait. I went this route as I didn't want to wade through a bunch of hets trying to get this trait.

Hi Bob

Beautiful snakes. Good idea on your project, get strait to the morphs.

Jason, my choice to cut to the chase has mostly to do with my own mortality; ain't no spring chicken here! LOL!

OK, thanks for clearing that up for me...
