Does anyone know what the heck I'd get from this cross. Are the albino genes allelic (sp?)? I was fantasizing that the F1 offspring would all be double hetero, as when breeding a snow corn to a normal corn, and then upon breeding the F1 together would hypothetically produce 1 snow Gophercorn, and the rest would be a mixture of normals, and red and black albinos of unknown genetic make-up.

You'd get a snake that looked somewhat intermediate between a gopher and a normal corn. If the mother is gopher, the eggs will be large and so will the babies. If the mother is corn, you have small eggs and small babies. I don't know that any F1's grow faster than corns, but there seems to be a fair bit of size variability in F2's and backcrosses. Scales tend to be intermediate between the keeled gopher scale and the smooth corn scale. Behavior tends to be corn-like, at least for my snakes.

If you do the mating and then either mate the offspring together or backcross to a snow corn (preferably male), you are going to get a bunch of very pretty animals.

If you cross the F1's together, the F2 should come out 9/16 full color, 3/16 amelanistic, 3/16 anerythristic and 1/16 snow. If you backcross to the snow parent or to another snow, the ofspring should come out 1/4 in each class.

Thanx for the response! Have you done this cross?

I bought a bull-corn hybrid. IIRC, the fellow said it was an F2. I've been mating her to corns. She lays huge eggs but most don't hatch. The babies that hatch are fertile. I've gotten progeny from a male mated to his sister, an amelanistic corn and a bullsnake. The male and his sister are both heterozygous for amelanism and I have gotten some very pretty offspring, particularly in the cross with the amelanistic corn.

Thanks again!
