When butterfly male sex-bias flaps its wings

In butterflies, sex is determined by chromosome differences between males and females. But unlike in humans with the familiar X and Y, in butterflies, it is the females that determine the sex of offspring.

Clues to chromosome crossovers

Neil Hunter's laboratory in the UC Davis College of Biological Sciences has placed another piece in the puzzle of how sexual reproduction shuffles genes while making sure sperm and eggs get the right number of chromosomes.
