I know that this might be a really stupid question. I am not looking for someone to give a cocky answer. I have just been browsing the classifieds on kingsnake for a redtail boa, and some classifeds say that they have a 66% heat for albino redtail boa, or a 100% heat. Does that mean that the snake could morph or change color when older and look more albino. Thank you for your help!

100% hets are from breeding either an albino x het(gene carrier) or albino x albino. The 66% hets are the normal appearing offspring from the afore mentioned 100% het pairing combos.

Albino x albino actually gives you all albinos, no hets.

>>100% hets are from breeding either an albino x het(gene carrier) or albino x albino. The 66% hets are the normal appearing offspring from the afore mentioned 100% het pairing combos.

you get 100% hets from albino x normal

Hi. No the orinal snake will not change. It means it has the gene for albinism in it and if bred back to an albino or a 100% het albino in that litter you should produce some albinos.It gets complicated but theres plenty of info on this online. Hope thaat helps. Debbie

just to add, the 100% hets would also look normal. They just carry the gene to make albinos but do not express the trait themselves.
het is short for "Heterozygous"
See the link below to learn more about morphs and trait expression. This is for corn snakes, but is a good place to start.

It's "het" (short for heterozygous), not "heat".

Heterozygous is a genetics term meaning that a the two genes in a gene pair are not alike. As the ads are referring to het for albino, they mean that one gene in the gene pair is an albino gene and the other gene is a normal gene. Boas that have an albino mutant gene paired with a normal gene look normal, like boas that have two normal genes in the gene pair.

If an animal that has a mutant gene paired with a normal gene looks normal, then the mutant gene is recessive to the normal gene. If an animal that has a mutant gene paired with a normal gene does no look normal, then the mutant gene is dominant to the normal gene. Most (but not all) mutant genes are recessive to the normal version of the gene.

Boas that are het for albino do not change their color. But they can produce albino babies if mated to an albino or a het albino.

Boas that are 66% het albino have a 66% (2/3) chance of being heterozygous albino and a 33% (1/3) chance of having two normal genes instead. Such snakes are generally less expensive than a het albino.

A 100% het albino is a long way of saying het albino. These are known for certain to be het albino.

Hope that helps.
