Under laboratory conditions, female guppies are able to store sperm for up to a year, potentially allowing them to produce offspring even if the males are no longer around.

Evolutionary Genetics: The Evils of Abstinence From Sex

The evolutionary significance of sexual reproduction and genetic recombination is a long-standing puzzle. Some recent experiments on Drosophila show that a lack of recombination can impede adaptive evolution.
