Sex ratios and penetrance by sex determination system. a Sex ratio by sex determination system. Dashed line indicates a 1:1 sex ratio, with values lower than the line indicating a female-biased sex ratio, and those above the line a male-biased sex ratio. (LG13 ZW, n = 8 families, 63 males and 115 females total; LG5-14 XY, n = 10 families, 115 males and 83 females total; χ 2 test for divergence from expected 1:1 sex ratio: *, p = 0.023, χ 2 = 5.2; ***, p < 0.0001, χ 2 = 15.2; LG13 ZW and LG5-14 XY family sex ratio differ from each other, p = 0.0053, Welch’s unequal variances t-test). b Penetrance by sex determination system, not significant
