I have 1.1 bull snakes and really dumb about genetics. my male is het for hypo. my female is hypo. now they are from the same clutch and mom was a hypo het for albino. and the dad was a snow.any ideas on what I would get breeding these to together?and with all these genes floating around between them are they considered triple hets? or is there such a thing? sorry if these questions are common knowledge but i Really have no idea.
Thanks,
Greg

I could tell you if I knew what mutants are required to make snow in bullsnakes. I'm guessing albino and something else other than hypo.

I can tell you that there is such a thing as a triple het. A snake that is heterozygous for two independant mutants (for example, heterozygous for albino and heterozygous for hypo) is a double het. A snake that is heterozygous for three independant mutants is a triple het. Your male may or may not be a triple het. He's a double het because he is heterozygous for albino and heterozygous for hypo. He's also fot a 50% chance of being heterozygous for whatever combines with albino to make snow. Your female is hypo, heterozygous albino, and has a 50% chance of being heterozygous for whatever combines with albino to make snow.

Possible result from this mating include (but are not limited to) albino, hypo, and snow. You could also get one or more snakes that are both albino and hypo, but I'd assume they would look albino.

Speaking from corn snake genetic knowledge:

For a clutch to contain a het hypo male and a female hypo, if the mother was hypo het albino, the dad was a snow he would also have to be het hypo. This being true, your snakes then would be also het albino and anery.

So you should be able to produce (ignoring het) snows, amels, anerys, hypos, and ghosts.
