♀M/♂P females from heterospecific crosses are more likely to be dysgenic than ♀M/♂P females from conspecific crosses.

Females with atrophied ovaries are more common in heterospecific than in conspecific crosses in this direction of the cross. Each row shows a type of cross. Temp (°C): Temperature (°C); Mean: number of nondysgenic females; CI: Binomial confidence interval. We used two-sample tests for equality of proportions (2sEP) for all comparisons and adjusted the P-values with a Bonferroni correction.
