In addition to the other web sites listed, you might try Serpwidgets' site. It is better than most. It is for the corn snake, but the principles are the same with corn snakes, boa constrictors, fruit flies, corn plants, etc. The major bad point is that it does not cover dominant and codominant mutants, like salmon (aka hypo) in boa constrictors, tiger in reticulated pythons, and spider in ball pythons. However, once you understand how to work with recessive mutants (like albino and pied in the ball python), learning to work with dominant mutants is not particularly difficult.
On the other hand, I don't know of any web site that is as thorough as a genetics text. Elrod and Stansfield's book, Schaum's Introduction to Genetics, is inexpensive. And I like its problem-oriented approach.
