Cull Bucks

Interesting link.
Culling to improve genetics is likely one of the most hotly debated topics among deer hunters. How often have you heard “that spike buck is genetically inferior.” Or, “I culled that buck to get him out of the gene pool”? Heck, you may have even said this yourself! In this episode we listen to deer biologist Donnie Draeger of the Comanche Ranch in South Texas as he describes the results from a landmark, 13-year study, designed to answer this question once and for all – to determine if culling can be used to “improve” genetics and increase the average antler size of bucks.
After 7 years of removing bucks with below average antler size (i.e., culling) the average antler size per age class did not improve. In fact, in the area where culling was most intense, where culling began with the yearling age class, the buck population began to crash. Most people would think this level of culling, which allowed only the large-antlered bucks to live and breed, would result in production of super bucks! Instead, the effects...

This is important because, whitetail genetics are similar to human genetics. For instance, a buck is born with an “X” chromosome it gets from Mama, and a “Y” it gets from Daddy (if the deer gets two “X” chromosomes, it’s a doe). The “Y” chromosome baby bucks get from Dad is smaller in size and carries less genetic information than the bigger “X” the buck gets from Mom. It breaks down to about 75% of the bucks genome comes from Mom, and about 25% comes from Dad. The end result is that the bucks Mom is more important than the bucks Dad.
