Thoughts on cinnamon and enchi being allelic?

[paulh]

Linkage wouldn't make sense for the results people get. If linked, a Cinnamon Enchi would produce a bunch of normals and Cinnamon Enchi's and rarely any with one or the other. because they would be passing down together from the same parent. Not to mention producing a Cinnamon Enchi in the first place would be more difficult than average odds.

It's been way more than a few clutches at this point to test the theory.

Gene symbols:
E = enchi mutant gene
e = normal gene
C = cinnamon mutant gene
c = normal gene

Chromosome pair of a cinnamon enchi from a cinnamon x enchi mating:
---------e------C---------
---------E------c---------
This is a trans linkage, because the two mutants are on different members of the chromosome pair. Almost all of this snake's babies (if mated to a normal ball python) would be either enchi or cinnamon.

A cis linkage would put the two mutants on one chromosome and the two normal genes on the other chromosome.
---------E------C---------
---------e------c---------

You are writing about a cis linkage, and what you wrote is true.
I was writing about a trans linkage, which gives totally different results.

I have not seen the results of any cinnamon enchi x normal matings. By all means beat me into submission with numbers. But to be convincing, the data must include genotype of male, genotype of female, is female virgin, total number of babies, number of cinnamon enchi babies, number of cinnamon babies, number of enchi babies, number of normal (neither cinnamon nor enchi) babies. The number of clutches means nothing. If possible, get at least 100 babies in the data.
