Figure 2.—

Effect of female genotypes at the beginning of an inbreeding experiment (mother–son mating followed by sib matings) on the predicted proportions of diploid males among fertilized offspring under CSD with three independent loci. All females are heterozygous at all three sex loci (bottom, solid line), which is the assumption made in our other predictions, or various fractions of the females used to start experiments are heterozygous at one or two of the three sex loci and homozygous at their other locus or loci (females must always be heterozygous at least at one locus because homozygosity at all three loci results in diploid male development). When 100% of females are heterozygous only at one of three sex loci, predictions are identical to those under sl-CSD (top, thick solid line).
