Homozygous Spider Morph

[paulh]

Exactly this is what I have been saying. One problem though, there are no homo dominant traits in ball pythons and thats what I am talking about (except for the one pin is suppose) so statistially speaking they should pass on the dominant trait to all their offspring if they are dominant but they dont exist so they dont. Its all great in theory and it works out on a punnett square but in application there are no homo dominant balls in application, except the one pin apparently.

I differ with this post for the following reasons:

1. The existence of one homozygous pinstripe ball python means that more can be bred.

2. The lesser pastel mutant gene is codominant to its normal allele. The mojave mutant gene is codominant to its normal allele. The lesser pastel gene and the mojave gene are alleles.

A snake with two lesser mutant genes is a blue-eyed white. A snake with a lesser mutant gene paired with a mojave mutant gene is a blue-eyed white, like the homozygous lesser snake. A snake with two mojave mutant genes is mostly white but has some pigment on its head.

Therefore, the lesser platinum mutant gene is dominant to the mojave mutant gene, and the mojave mutant gene is recessive to the lesser platinum mutant gene.

Homozygous lesser x homozygous mojave -->
100% blue-eyed white (with a lesser platinum gene paired with a mojave gene)

By the way, the royal python genetics field is a tiny ghetto compared to fruit fly or mouse genetics. Both of those species have plenty of dominant mutant genes. Also, the salmon (AKA hypo) gene in boa constrictors and the stripe gene in California king snakes are dominants.
