A Complex Genetic Network Controls Whether Fruit Flies Need to Sleep in

Caption

The figure depicts allele frequency changes in sleep-associated polymorphisms across generations of artificial selection for short and long sleep in Drosophila. The top set of bars shows how allele frequencies become more extreme, migrating towards 0 (dark blue) or 1 (dark fuschia) for generations 0, 1, 2, 5, 8, 10, and 12 of selection for short sleep. The bottom set of bars show similar changes in allele frequency for flies selected for long sleep.
