Semen secrets: How a previous sexual partner caninfluence another male's offspring 

Scientists have discovered a new form ofnon-genetic inheritance, showing for the first time that offspring can resemblea mother's previous sexual partner -- in flies at least. Researchersmanipulated the size of male flies and studied their offspring. They found thatthe size of the young was determined by the size of the first male the mothermated with, rather than the second male that sired the offspring.

The idea of telegony -- that a male can leave amark on his mate's body that influences her offspring to a different male --originated with the Greek philosopher Aristotle. It was a concern to royalty inthe 1300s and still popular as a scientific hypothesis in the 1800s butrejected in the early 1900s as incompatible with the new science of genetics.
