Yes - Virtually every doe gets pregnant, but a few bucks father most of the fawns. Does that run the hardest have their fawns fathered by the fittest bucks on average. Thus, these does pass down the genetics for running to their offspring. Those managing for trophies often try and keep competition for does high by removing a lot of does. Keeping doe densities low also means lower herd densities and good herd health. Domestic animal breeding is controlled by humans. You don't see Holsteins or broiler chickens running wild.
