I have thought of this possibility if I ever did genetic testing, finding out about different parentage could be shocking. It would be interesting to know about. I also shudder at the fact that it's yet another way for the government to track everyone. Probably almost everyone has enough other people already sequenced that we have almost total coverage already.
I found a sister this way. We both happened to move to the West coast; about two hours drive apart. 10/10 would do again
So beautifully written
Paternity testing should be mandatory at the birth of the child. Adultery is socially destabilizing, and should be discouraged.
Awareness of adultery seems to be the societally-destabilizing part of that concept.
