Animal behaviorists have shown that if a female pronghorn picks the right male, her fawns will grow faster than normal and have a much better chance of surviving. They suspect that female pronghorns are actually choosing mates with the lowest burden of so-called deleterious mutations. They haven't had a good way to prove this theory, but thanks to the growing availability of next-generation DNA sequencing, they may finally have a chance. This story and the ones accompanying it are part of a collection this month reflecting on the 10th anniversary of the publication of the human genome, which is gathered here.
