Can anyone please give me some infromation of het ball pythons. Also possible hets. Just general information like what will the baby balls turn out to be. What does a het produce when mated to a normal? or a possible het to a normal. Is Is it possible to get the morph your looking for by buying a possible het and mationg it to a normal

Thanx

het to normal will make- 2 hets 2 normals or 50% possible hets
het to het will make- 1 purebred 1 normal 2 hets or 1 purebred and 3 66% possible hets
a posible het bred to a normal will only make possible hets

This is true for recessive mutant genes. It is not true for dominant and codominant mutants like pastel and spider.

For dominant/codominant mutants:
het x normal --> 1/2 the babies are hets, 1/2 the babies are normal. There's no such thing as a possible het from this mating when the mutant is dominant or codominant to the normal gene.
het x het --> 1/4 homozygous mutant, 2/4 heterozygous mutant, 1/4 normal. If the mutant is dominant, you get 3/4 with the mutant appearance and 1/4 normal. If the mutant is codominant, you can distinguish the hets from the homozygous mutant animals.

I believe that if a possible het for a recessive mutant gene isn't worth testing to see if it really is a het, then the babies should be sold as normals.
