Telegony's Back, Baby
Scientists have discovered a new form of non-genetic inheritance, showing for the first time that offspring can resemble a mother's previous sexual partner -- in flies at least. Researchers manipulated the size of male flies and studied their offspring. They found that the size of the young was determined by the size of the first male the mother mated with, rather than the second male that sired the offspring.
The idea of telegony -- that a male can leave a mark 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 in the 1300s and still popular as a scientific hypothesis in the 1800s but rejected in the early 1900s as incompatible with the new science of genetics.
So don't fuck even "reformed" coal burners. Or fly hos, for that matter.
