I bow to what others say, especially Brutal Attack, technically they do interbreed occasionally. But I personally think it's damned rare, in the herds I hunt.

I think the incidence of interbreeding get wildly exaggerated.Some guy sees a whitetail with a sticker point off a tine, and yup that there's one of them crossbreeds.

I hunt an area with a true intermix of whitetails and muleys out in eastern MT. Right now, after a rough winter in '03/'04 its 2:1 muleys to whitetails. Before that, it was 1:1. The deer intermix, but with whitetails tending to be closer to alfalfa fields and muleys a little more toward the rough broken country. It's pretty clear whitetails take priority. They take the prime habitat and the muleys fill in around the edges.

Ihave watched rutty muley bucks approach whitetail does with sex on the brain, then turn off when they see it's a whitetail. I've watched the same show with a rutty whitetail buck, and he'll alsoturn and go away. I've seen near-fights between muley and whitetail bucks, but I've never seen crossbreeding or any deer that looked like a cross. I don't doubt that once every decade somebody gets his wires crossed and humps the wrong doe, but it's really not worth all the time some people spend talking about it.

Just my opinion, applied only to the areas I hunt.
