Fig. 3. D. melanogaster males prefer to court conspecific males over females of a distant species.

Wild-type D. melanogaster males courted females from other species with varying degrees of intensity as measured by the courtship latency (A) and the courtship index (B). (C) In choice assays, D. melanogaster males of all tested genotypes chose to court conspecific males over females of D. willistoni. Boxplots represent the distribution of male mating choices. No significant differences were found between feminized flies and the parental controls. *p<0.05.
