Introgression experiments corroborate a maternal genetic effect on hybrid mortality. a Introgression crosses. Nearly complete F1 hybrid mortality requires the R3 nuclear DNA, as evident by introgression of the R3 genome into the UT cytoplasm. Data are shown as mean number of adult females ± SE, K-S test, **P < 0.01. b Introgression-heterozygote crosses. F1 hybrid mortality is partial when mothers are heterozygous for the incompatible R3 and compatible UT genotypes. Data are shown as mean number of females ± SE, K-S test, **P < 0.01
