Incestuous sisters: mate preference for brothers over unrelated males in Drosophila melanogaster.

The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny. We investigated male and female mate preferences with respect to rela...
