Figure 1

Expected proportion of female progeny from hermaphroditic maternal parents and female maternal parents compared to expected population-level proportion of females. The different panels illustrate the effects of varying frequencies of occurrence of cytoplasmic male sterility (cms), inbreeding (f), and frequency of nuclear male restorer alleles on these sex ratios. Panels ‘a’ and ‘b’ consider the dynamics with high or low level of cms, respectively, where there is no inbreeding (as with a very large population). Panels ‘c’ and ‘d’ show the population dynamics considering these two levels of cms, but with an inbreeding coefficient of 0.5 as may be expected in a smaller population.
