This picture may look like something from a circus but follow me here and this is how the genetics should be playing out……..In this example we have three distinct populations……the red, the blue, and the green……..The big circles represent how the doe genetic distribution is occurring and the small dots are how the buck distribution occurs. Now the way nature would work if we took these three populations and dropped them inside the King Ranch in this manner to restock it (lets assume its void of deer for our example) Natural selection is likely gonna choose for one of the three doe circles to outcompete the other ones over time if there was any distinct advantage that one group had over the other in fawn survival…….However, if we take this same scenario and we drop it into Alabama and we divide the blue and the green by a major interstate highway on this side and habitat fragmentation on that side….. then they would likely be so divided by these barriers that the green and blue doe genetics essentially exist in isolation of one another with a small amount over overlap variance….It would be very hard for each zone to impact the other one because any female mortality inside of the zone is most likely going to be filled back in by expansion from within that zone and not through immigration from outside……the interstate and fragmentation virtually shuts that down from the female side of things.
