RE: pie-bald
I beg to differ. The recessive gene here is for pigment. I have seen many piebalds as a taxidermist, as well as many more as a deer farmer. I have seen the sloped muzzles, the small palmated antlers as well as the bowed and short front legs on piebalds...incidently, at the same rate I see it on typical brown colored deer. I have personally seen P&Y 2 and 3yr old piebalds in the wild, hunter harvested. I have seen 300 plus lb pieds in captivity with near B&C antlers. Seneca Army Depot in Romulus NY has a herd known across the country for being all white pieds. Michigan has similar animals there.
I say enjoy these unique animals, and harvest one if you choose. I would not, however, suggest eradicating them as genetically inferior animals.
