[ X & Y chromosome stuff ]
Which reminds me of something I wanted to ask the group ...
In Science News a few weeks ago, there was an article about finding the
gene on the Y chromosome that causes the individual to develop as a
male. In the article, they said that they had narrowed it down by
studying individuals in which the "maleness" gene had been swapped onto
an X chromosome, and individuals in which the gene was missing on a Y
chromosome -- XX males and XY females, respectively.
Until reading this article, I had never heard of such a thing. (This
isn't XXY or XYY, which I had heard of.) How common is this? Are XX
males and XY females generally otherwise normal? Are they fertile?
