Observed and simulated expected distributions of progeny segregation proportions (k) at three supergene-associated loci. The expected values were generated by a simulation model that takes into account specific sample sizes and assumes that departures from Mendelian segregation ratios arise by chance. The segregation proportions (polarized k) refer to the supergene-linked alleles C294⁹², Gp-9^b, and, for locus i_126, the specific allele on the supergene in each progeny (i_126²³⁰ in 60 of 85 [70.6%] segregating progenies). Hatching indicates proportions of progenies with observed k values that depart significantly from Mendelian ratios based on the binomial probabilities. Values on the x-axis denote bin maximum values of k
