>>Does anyone breeding F1's ever have one randomly come out? Or are they more locality based?

Back in the day it used to happen all the time. There was more than one WC melanistic, and that gene seemed to be prevalent in the other WC's from that area (much like Blond subocs).

Melanistics lost popularity and soon became less common in the hobby.

Every single instance I have personal experience with points to simple recessive, though some report that the gene behaves more like a super gene. That could easily be explained by poly-paternity or stored sperm however, so in my mind I am reluctant to concede that there are two melanistic genes in the hobby, though it is a possibility.
