Breeding Boas

[bighog85]

So I have a guy that bought 1.1 columbians from Jeremy Stone as neonates that were supposedly 100% het for kahl-strain albino. So far he has produced two litters and there have not been any albinos. He is offering to essentially give them to me but I was wondering if there was any chance of them producing albinos or does this probably mean that they are not going to. I do not know much about genetics so I wanted to see what you all thought. Jeremy Stone is a pretty reputable breeder from what I know so I don't see him messing that up.

There will be far more experienced comments than mine on this subject but I do know albinism isn`t something that happens throughout a litter, you`d only expect a couple out of a whole litter as far as I know so there`s still a chance you could get albino`s I think. If not, try keeping some offspring back and breeding them.....

There's always a chance of them producing albinos, IF they are truly 100% het for albino. What you will have with two hets breeding is each snake has 1 albino (a) and 1 normal gene (A)

The Punnett Square looks like this:

A a
A AA Aa
a Aa aa

That means that there are 3 possibilities for each baby: normal, normal het for albino, or albino.
Each baby has a 50% chance of being het for albino, a 25% chance of being completely normal, and a 25% chance of being albino. There is, as far as I know, no way of telling the normal from the het babies, so you'd have to list all babies as being 66% possible het (there's a 2/3 chance every normal-looking baby is het, since there's a 50% chance of het and 25% of full normal in the square).

Remember that those chances are for every single baby, not for a whole litter, so you could technically breed two hets together every year and never see an albino, although the chances of that are pretty rare. If they are true hets, they should eventually produce an albino baby, although it may take several litters. If you want to prove them out, I suggest finding someone you know who has a pair of albinos. Breed each of your hets to the opposite sex albino, and if you get any albino babies in the litter, yours are indeed hets.
