What can dropped tines reveal about a buck's overall genetics?

Tine Development Genetics

Research on whitetail deer genetics has shown that dropped tines are often linked to a specific genetic variation that affects the development of the pedicle, the base of the antler, and the tine itself. Studies have identified that bucks with dropped tines often have an incomplete or missing copy of the BMP2 gene, which plays a crucial role in the formation of the antler’s pedicle. This genetic variation can impact the buck’s ability to grow a full set of antlers.

Implications for Hunting and Management

Understanding the genetic factors behind dropped tines can help hunters and wildlife managers identify potential weaknesses in a buck’s genetics. By tracking the occurrence of dropped tines over time, researchers can gain insights into the genetic health of a deer population and make informed decisions about hunting and management practices. For example, a study in the 1980s found that 14% of bucks in a Michigan deer herd had at least one dropped tine, suggesting that this genetic variation was relatively common in the population. By monitoring the frequency of dropped tines, wildlife managers can assess the impact of hunting and other management practices on the deer population’s overall genetic health.

Hunting Strategies

For hunters, recognizing the genetic factors behind dropped tines can inform their approach to hunting. For example, a buck with multiple dropped tines may be more prone to injury or stress, making it a more vulnerable target. Hunters can also use the presence of dropped tines as a cue to evaluate a buck’s overall size and potential age class, as larger bucks are more likely to have developed antlers with fewer genetic anomalies.
