Chromosome and mitochondrial segregation and maternal contributions in C. briggsae × C. nigoni hybrid crosses. In all panels, C. briggsae and C. nigoni genotypes are indicated in red and blue, respectively. In F1 hybrids, maternal chromosomes are shown above paternal chromosomes. In panels D and E, the v188 mutant allele of cbr-him-8 is indicated by a closed circle on chromosome I. In panel E, an open circle on chromosome I indicates that half of F1 hybrids were expected to be heterozygous for cbr-him-8(v188). Diagrammed are crosses between (A) C. nigoni females and C. briggsae males, (B) sperm-depleted C. briggsae hermaphrodites and C. nigoni males, (C) PB3500 cybrid females and C. briggsae males, (D) sperm-depleted C. briggsae cbr-him-8 mutant hermaphrodites and C. nigoni males, and (E) sperm-depleted C. briggsae cbr-him-8/+ heterozygous hermaphrodites and C. nigoni males.
