**A: **For years, biologists believed exactly that-with the exception being in heavily harvested herds containing few, if any, mature bucks. In these herds, rutting activity is a free-for-all. However, recent studies using molecular genetics techniques have cast a lot of doubt on the conventional wisdom. These studies suggest that all bucks participate (or attempt to participate) in breeding activities, and even when there are mature bucks around, many young bucks do successfully breed does. Certainly, dominant bucks have the opportunity to claim dibs on any estrous doe they encounter. But remember, a buck will remain with an estrous doe for about 18 to 36 hours while she remains in heat. Any other does that come into heat at that time are available to subordinate bucks.
