Actually genetics has a lot to do with antler development and that was proven by the Kerr study. One of the critical factors that effects PA the most is the rate of antler development. Studies have shown it takes the average 1.5 spike three years before it catches up with the average 1.5 6 or 8 pt.

That means the average 1.5 buck doesn't live long enough to match the potential of the 1.5 6 or 8 pt. that gets harvested as a 1.5 buck.
