Infertility is far more common than traditionally imagined. We will study this in stalk-eyed flies, a classic example of sexual selection driven by female mate preferences for exaggerated sexual ornaments (male eyespan). The aim of this project is to characterize the genetic basis of infertility, predict the conditions under which it evolves, and study how females adapt to mitigate infertility.
