As far as I know, there might be one magazine article by Bob Clark about his albino ball pythons. And maybe one or two in Reptiles Magazine about ball python morphs. But I don't remember when.
I checked on the ball python book cited in an earlier post. Amazon says copyright date is 1997, so apparently there has not been an update. And 1997 is pretty dated as far as the genetics goes.
I've not see the Bartlett book, but I have seen a number of snake genetics web sites. Separating the genetics from the pseudogenetics requires some training in genetics which I didn't have when I was in 10th grade.
If this is for an English class, IMHO the object of the exercize is for you to learn how to learn to find material in the library and organize it. Ball python genetics is so narrow that very little has been published. I would recommend changing to a subject that has more material in the books and magazines in the library. Sorry to rain on your parade. Good luck.
