What ever happened to the Repository for Germinal Choice? Also known as the Genius Sperm Bank, it was the idea of one Robert Klark Graham of San Diego to collect and provide sperm from Nobel Prize Winners and other certified geniuses to raise the level of intelligence in the gene pool, generally. See today's "Where are they now?" story on the BBC by clicking the link above.
Current thinking in the field says that the genetic components of intelligence are passed down through the mother's side alone. Of course, Graham couldn't have known this back in the 70s. It was a nice try, though.
