After years of looking at DNA matches etc., a question only just occurred to me today. It is this. I inherited a pair of x chromosomes. One X chromosme, through my father, is from my paternal grandmother. (I am her sole granddaughter) The other from my mother. I only have one child, a son. He will inherit an X chromosome from me. But which one? Will it be the one I inherited from my paternal grandmother, or the one I got from my mother? Is that one of the random things DNA does when it passes down? I just makes me a little sad, thinking that I am her last chance at passing on her DNA, and it might not happen.
