Extended Data Figure 7: Sine song frequency phenotypes of 12 D. simulans wild-type isolates (blue) and 12 D. mauritiana wild-type isolates (orange).
From: Natural courtship song variation caused by an intronic retroelement in an ion channel gene

Open circles with lines represent mean ± s.d. Closed circles with lines represent mean ± s.d. of the means of all D. simulans (all_sim) and D. mauritiana strains (all_mau). P value by one-way ANOVA. All strains were recorded simultaneously through multiple recording sessions.
