First time breeding genetics question.

Okay, so I just go into the leopard gecko hobby and I'm really interested. I have a nice jungle bell albino female and I want to breed her to a mac super snow het for bell. Now would that combo be able to produce a jungle snow bell? From my crash course in leopard gecko genetics i got on google, I know the jungle gene is a line bred trait, and that a super snow bred to a normal (in this case the jungle bell) would produce 100% snows. If I am wrong please correct me. And that because the supersnow would be het for bell, that it would produce 50% bells, so in theory, should i not produce 50% snow bells, with or without the jungle gene? If so, could I then pair the hatchlings to get super snow bells with/without the jungle gene?

You're right that you'd get 50% Mack Snow Bells and 50% Mack Snows het Bell. The Jungle patterning will vary from baby to baby since it's line bred (polygenetic). Hope that helps.

Specifically speaking, each baby would have a 50% CHANCE of being bell. You could luck out and have lots of them be bell or not have many at all. Meaning if you had 10 babies you could get 8 bells or 2 or anywhere in between. But any that are not bell would be het bell. In your case, you'd have mack snow bells and anything else would be mack snow het bells. And yes, the jungle trait would be kind of all over the place since it polygenic.

Hopefully I didnt make it worse..lol.

With regard to the second generation pairings, any albinos you have will be snow so any male/female albinos from that original pairing will produce SS Bells for you.

Thank you for the replies, one last question. If I kept breeding jungle to jungle, would the proportion of jungle babies increase? Or is it going to be varied no matter how much I try?

I would guess it would increase but it's hard to know.
