Variation and evolution of male sex combs in Drosophila: nature of selection response and theories of genetic variation for sexual traits.

Genetics - 1 May 2008

Ahuja Abha, Singh Rama S

Abstract excerpt

We investigated the genetic architecture of variation in male sex comb bristle number, a rapidly evolving secondary sexual character of Drosophila. Twenty-four generations of divergent artificial selection for sex comb bristle number in a heterogeneous population of Drosophila melanogaster resulted in a significant response that was more pronounced in the direction of low bristle numbers. We observed a strong...
