It is possible that some of these examples are what is known as a hermaphrodite. In this case, a deer with the sex organs of both male and female. I can't remember what it is called if it possesses all the correct sex organs of a doe but has antlers too, or vise-versa. I've seen a few livestock borne this way. Unusual in nature? Yes. But most experienced livestock or animal breeders of registered lines have seen one-to-multiple. If it is less UNusual in whitetail, perhaps it is because they seem to be more family/herd group oriented and territorial than other ungulates in the deer family. This would make interbreeding more likely, which is the cause of the genetic condition. Just a thought.
