				Proportion of Mutations in Different Selection Intensity
Data Set	N2/N1	t/N2	α	Nes = 0–1	Nes = 1–10	Nes = 10–100	Nes = 100>
GSC	0.45 (0.19–6.71)	6.28 (5–4,681.86)	0.75 (0.45–0.85)	0.06 (0.02–0.09)	0.04 (0.01–0.20)	0.07 (0.01–0.53)	0.84 (0.20–0.96)
Sex-biased	3.10 (0.35–10)	5.00 (5–189.18)	0.86 (0.51–0.99)	0.02 (<0.01–0.08)	0.10 (0.01–0.17)	0.42 (0.10–0.85)	0.46 (0.03–0.82)

Note.—N₂/N₁, the estimated demography as the ratio of current and past population size; t/N₂, the estimated time of demographic change scaled by the current population size (N₂); α, proportion of nonsynonymous sites fixed by positive selection; N_es, strength of selection against newly arising mutations on nonsynonymous sites. 95% CIs are shown in parenthesis.
