The combination of parental ‘SD allele sets’ have a profound effect on the sex ratio of the offspring. Using bigenic genotyping data from the offspring groups analyzed by Bradley et al. (Supplementary Table 4 of [24]), we have created imaginary crosses using one male genotype with three different female genotypes. The parental genotypes were chosen in such a way that they could only produce a single genotype per cross that was among those detected by the authors. Wide range of sex ratios obtained and two opposite sexes with the same SD genotype both indicate a higher level of complexity than what could be explained by participation of just two loci in the SD process. On the pie charts, checkered background indicates males, and solid background indicates females.
