"Culling" does nothing but remove a deer from the population. You ABSOLUTELY CANNOT "improve antler genetics" by culling.
So bucks have no part of future antler genetics? If a doe is bred by a buck with "messed up" or inferior antler growth the doe does not have a chance of giving birth to a buck that will have "messed up" or inferior horns?
A bunch of different points to make on this topic:
First, bucks with "messed up racks," especially those with just one antler being "messed up," are usually due to injury to the antler pedicle, the buck's body, or to the growing antler while it was in velvet. Now antler-deformations caused by injuries to the growing antler or to the buck's body can fade away with time (not be repeated in future sets of antlers). But a deformed antler due to injury to the antler pedicle are usually permanent and often get worse with age (this is the most common cause for older bucks with one normal antler and the other antler being a malformed spike).
Second, the heritability (genetics) of antler characteristics is not well understood. It appears to be a very complex process, and not just a simple 50% from the mother and 50% from the father sort of thing. Although detailed studies have not been completed, the few studies that do exist show little relationship between father's and sons' antlers. In essence, all of the male offspring of a single buck will not produce simliar size/shape antlers, nor will any of the sons' antlers look like their father's in any measureable way. HOWEVER, the sons of a single mother often DO have similar antlers, in both shape and size. This
suggests the mother's genetics play a larger role in male offsprings' future antlers than their father's genetics.
Lastly, in a free-ranging situation, most yearling bucks disperse from their birth ranges, taking their genetics with them, and often traveling miles away from their birth range before establishing a new adult range. All of these "dispersing" yearling bucks are replaced by yearling bucks also dispersing from their birth ranges miles away, bring in their "new" genetics. So even if the link between genetics and antler size could be determined, most of the older bucks that use a given property
are not the offspring of the local bucks and does. The offspring of the local bucks and does left around their first birthdays and now live miles away. Because of this young buck dispersal process, you can never "concentrate" any male-based genetic traits in one area.
