I recently ran across this article regarding the expression of coat color genes in mice.
I noticed two things. The baby's environment can profoundly affect its gene expression, and the color genes affect the animal's metabolism.
How often does this sort of thing happen in herps? How would we know?
Much more seems to be known about rodent coat color genetics as opposed to those of reptiles, probably because breeding experiments are easier. And because more people care. There are something like 20 different known genetic traits in gerbils, some different alleles of the same locus. Perhaps herps are just as complicated, we just don't know it yet.
So what I'm saying is this color genetics thing is a very very complex subject, and it makes my head spin, personally. The major ball and corn breeders seem to be interested in approaching the subject scientifically, so I'm sure interesting discoveries will be made in the near future.
article- hope it works
