To the best of my knowledge and belief, there is no blood test or similar test for amy mutant gene in boa constrictors or any other snake.

To test for a recessive mutant gene, such as albino, you would mate your snake to a snake that is homozygous for that recessive mutant gene. IOW, you mate your boa to an albino boa. If there are 17 or more babies, and none show the mutant (albino) appearance, then your snake does not have that mutant gene. This gets expensive fast.


You do not have to test for a dominant or codominant mutant gene like hypo (salmon). If you cannot see the effect of the mutant gene, then your snake does not have the mutant gene.

Hope this helps.
