Questions About Producing Super Ball Hybrids

[paulh]

Is this true? I've always considered recessive and dominant to be relative to the gene it's paired with. So in a Ball, the 'fire' gene is dominant to the 'normal' gene therefore it's visual. But in the Ball to Blood hybrid, is it not possible for the Blood's 'normal' gene to be dominant to the Ball's 'fire' gene thereby making the 'fire' gene recessive in the hybrid animal.

It is possible for the ball python's fire gene to be recessive to the blood python's normal gene. But that is far less common than acting the same way as with the ball python normal gene. Experimental data is needed to be certain.

This is true. If you think about it, the WT gene (or an ortholog of it) will be in each species because they have a common ancestor that had the gene. This is exactly the reason you can get an Albino BurmBall, both species carry the same albino type gene. ....

One of my genetics profs had an albino pigeon x ringneck dove hybrid (different genera). He was always careful to say that the albino mutants in the two species were alleles rather than identical. There are many ways to screw up a gene, and only DNA sequencing could show whether the two mutants were identical. The domestic pigeon genome either has been or is in the process of being sequenced. I don't think the dove genome has been sequenced yet.

By the way, Aedryan Methyus, an Albino Ball could be compatible with either a T-negative or T-positive Blood. I am using the T-neg and T-pos terms in the loosest possible way. In corns, the amelanistic mutant gene (T-neg, no melanin) and the ultra mutant gene (T-pos, less than normal melanin) are compatible. In boa constrictors, the Sharp albino mutant gene (T-neg, no melanin) and the boawoman caramel mutant gene (T-pos, less than normal melanin) are compatible. So the equivalent of Sharp albino in one species and boawoman caramel in the other would be T-neg to T-pos compatibility. Sharp albino equivalent in both species would be T-neg to T-neg compatibility.
