My mother and her brother both share 11.9% identical DNA with their first cousin. As the next generation from these three, my share of the identical DNA should be cut in half. My mother's cousin and I match 5%. This percentage is on the lower end of the predictable amount shared. We should be grateful for this because the lower percentage bumped us into a second cousin prediction and allowed him to be revealed in my account as a match, enabling me to reach out to him.
For illustration purposes, my father and his first cousin once removed match at 6.71%. I match this first cousin twice removed at 4.44%, which is just short of the 5% I share with my first cousin once removed. That is how random DNA inheritance works. You end up carrying more DNA from some ancestral lines than others.
Guess some ancestors make a bigger contribution to our "nature" component than others just like some make a bigger contribution to our "nurture" component.
