Bad boys, wild girls, and mating patterns

May 26, 2011

Imagine a world where the bad boys and wild girls are genetically determined, and more, easily recognized. Say, by a shock of white down the top of their head. How would that affect mating patterns? Would the wild girls prefer the bad boys? Or would they crowd out the good girls for more reliable mates? It turns out that world really exists. If you’re a white-throated sparrow. GrrlScientist has a fascinating post on how that works, and on the genetics behind it. Though it’s not so much about genes as their order.
