Sorry for my late reply as well. I have been out of town for a few days. Hope your calculus test went well.

I don't keep B. subocularis and have never seen one of these adults in person, so I'm only commenting based on my background in genetics.

But my understanding is that when it comes to adult phenotypes, we are not seeing any intermediate forms between silver & normal, whether in captive bred populations or in wild populations known to have Silver specimens.

If so, this makes me doubt additive genetic effects.

Of course one can have additive genetic effects and still have discreet phenotypes (i.e. non-continous variation) but this is thought to be less common. Can't think of an example off the top of my head.

So again, are you saying that there are intermediate forms between silver and gray B. subocularis specimens?

If so...

Is this in the wild?

Is this is captive populations?

Again, my understanding is that in captivity Black Gap specimens have either been silver or normal, with no intermediate forms. At least when comparing adult phenotypes.

And given the random nature that silver babies have showed up in captive breedings my gut reaction made me think some sort of polymorphism.

Thanks for any information. I have no vested interest in this discussion but am curious as to what is going on.
