| sexual selection for size and symmetry in a diversifying secondary sexual character in drosophila bipectinata duda (diptera: drosophilidae). | results of intrapopulation studies of sexual selection and genetic variation and covariation underlying elements of the sex comb of drosophila bipectinata are presented. the magnitude of the sex comb, a sexual ornament, varies significantly among australasian populations, motivating research into the evolutionary mechanisms responsible for its incipient diversification. the comb is composed of stout black teeth on the front legs of males arranged in three distinct segments: c1, c2, and c3. signi ... | 2004 | 15119443 |
