I am in college as of now and am currently majoring in wildlife biology. We have not discussed whitetails, but I think I can help a little. It has everything to do with dominant and recessive genes and x and y chromosomes and all that hard scientific stuff. I believe the doe is, in most cases, the recessive gene. The chromosomes mix almost equally for everthing from body size, color, everything except racks generally speaking. This is because the does obviously dont usually have racks. This accounts for does with racks. That is when a doe fawn recieves an xx or a yy gene makeup, as opposed to a xy or yx. This along with the proper nutrients helps a doe grow antlers. Overall the buck himself has more to do with the rack because he usually has the dominant gene for growing antlers. It's really tough to change the genetic makeup of racks in an area. We have a lot of basket racks we're trying to kill and leaving the younger wider ones. It will take time, but the gene pool will eventually be altered.
