Male progeny production. Offspring production of hybrid males relative to pure species and heterospecific crosses. Error bars indicate standard errors, and the numbers within the bars are the sample sizes. “Subo” refers to D. suboccidentalis, “Occ” refers to D. occidentalis, “F1(SxO)” are F1 hybrids from a D. suboccidentalis female, and “F1(OxS)” are F1 hybrids from a D. occidentalis female.
