Evolution of sexual isolation during secondary contact: genotypic versus phenotypic changes in laboratory populations.

The American naturalist - 1 Apr 2005

Alipaz Julie A, Fang Shu, Osada Naoki, Wu Chung-I

Abstract excerpt

We monitored the phenotypic and genotypic changes that occur when two behavioral races come into contact in laboratory populations. Drosophila melanogaster from Zimbabwe and nearby regions (Z type) show strong but asymmetric sexual isolation from their cosmopolitan counterparts (M type). Crosses of Z females and M males do not take place readily when other choices are available. At least 15 loci are known to...
