Y chromosome

Men who think that size really matters should probably not think too hard about the Y chromosome. This bundle of genes is the ultimate determinant of manliness, and it happens to be a degenerate runt.  Over a few hundred million years, it has shrunk considerably, jettisoning around 97% of its original genes. Where it was once a large library of genes, now it's more a struggling independent bookstore. This loss of information defined the youth of the Y chromosome but nowadays, things are different.

Male adoptees are getting their DNA tested and getting information about their possible surnames. According to the BBC news: At least 30 men registered with US consumer genetic testing firm Family Tree DNA have found their…
