well I guess with what we know right now, it can't just stay on one Z, because we would be seeing a ratio 25% coral glow female, 25% coral glow male, 25% normal female, 25% normal male. so something else has to be going on. it can't just be a "simple" sex link trait at all.Originally Posted by dr del
Surely if it was on the Z chromosome then you would have a higher chance of the males in the clutch being bananas than the females?
Isn't it more likely to be tied to the W chromosome - and it neededn't be in the sex chromosome directly but in DNA that gets passed along with it?
They have found satellite DNA in the more advanced snake species already and some was common to both the Z and W chromosomes and some was specific to the W chromosome.
Say it was tied into one of the ones that was thought to be common to both but altered it slightly so it isn't.
so while both the Z and W have A version that can be passed along they are not the same version?
Or is that just horribly complicating the whole thing? It could be completely wrong in any case of course.

But atleast what we are told is their usually seeing 50% female coral glow, 50% male normal, then the ever so rare male coral. it sounds like the male corals never make a normal females. ....... again real statistics would help us make better theories.
I think I understand what your saying, I'm curious how the hell do you prove it or disprove it lol. Maybe with more generations and some good record keeping we might be able to see how this gene jumps around. might be something like If male/female Generation 2 snake came from male female generation 1 snake with the gene, then generation 3 predicted offspring will be XXX.
