I have been thinking about this and there is just no good explanation for the male being either a "male maker" or a "female maker" without the allele for B/CG causing failure in the W or Z respectively.
I went on iHerp, the only tracking site I know of, and found two coral glow outcross (meaning not breeding for a super coral glow), but the outcome of the clutch was not available.
When a "male maker" or "female maker" is bred to a normal, what is the sex ratio of ALL of the litter? Is it near 50/50 or is it gender heavy in favor of the sex of the b/cgs?
Have the normal females been bred to other snakes? Are the ratios similar? Has the male been bred to other normal females with similar ratios?
Where are we actually getting the data for this "male/female maker"? How many breedings are required before one can say it's a gender maker, not just luck of the draw on one clutch?
Makes me want to go back to school so I can do a Masters Thesis on this.....
