I have seen mulies and whitetails together out on the prairies of CO and many, many years ago I shot a mulie/whitetail cross. It was a small meat buck and it was running with 2 whitetail does. It ran really weird and had a funny tail that was kind of shaped like a whitetail but only as long as a mulie tail and it had a dark grey patch on the forehead where a mulie has the black patch. I took it to the CO DOW in Brush CO and they took a tissue sample and it came back as a cross. I kind of wish I would have kept the antlers but the dog used them as a chew toy. I seriously doubt I will ever take another.
