That donor produces pretty women. But the fellows look, well, rather gay. Perhaps there really is a gay gene?
Also there seems to be a strain of neuroticism in there.
But that may also be all from the various mothers. The mothers too would have things in common, similar problems, to go the sperm donor route in the first place.
And then there is the problem of being fatherless.
I think what youre seeing is mostly the effect that our environment has on us. All of these people have the same biological father. Probably most of them were raised without a man in their house, seeing as they were often brought up in same sex marriages. However, some might have a grandfather or uncle that couldve been around occasionally as they grew up.
What I found interesting is that these kids are all learning about sibling relationships in a totally unnatural way, something that is pervasive in their lives. Its kind of sad.
More likely that a great percentage of them were raised by lesbians, and the rest by infertile male+female couples.
