Female preferences between incipient species of Drosophila athabasca reveal divergent closed functions, epistasis, and segregation of veiled preference alleles.

Abstract excerpt

Theoretical models typically assume that speciation is driven by divergence in female preference functions for secondary sexual traits. However, little is known about how these functions diverge between incipient species. This study used song playback experiments and mate choice tests to characterize female preference functions for divergent male courtship songs between two incipient species of Drosophila...
