There are more and more areas out west where whitetails are encroaching on the mulie's habitat and most people don't like it. Whitetails are the more dominant species and can push mulies right out of their living area. A whitetail buck will also breed a mule deer doe and you then have a hybrid cross. Here's a picture of a hybrid buck that has the body color, ears, and tail of a whitetail, but a screwed up mule deer type rack. Sorry the picture isn't the best, but there was very little light left the evening we saw him to get pictures.This was where we hunt on the west side of the BigHorn Mountains in northcentral Wyoming. The whitetails are taking over down through the lower river drainages and agricultural areas out there. So far they aren't moving up to the higher areas where there are still just mulies.
