Table 1. Sex-specific fitness for each genotype (wf and wm for females and males, respectively).

A m, A mA m A mA f A f, A fA f
B1, B1B1 wf = 1 – sf wf = 1 – kfsf wf = 1
wm = 1 wm = 1 – kmsm wm = 1 – sm
B1B2 wf = (1 – sf)(1 – htf) wf = (1 – kfsf)(1 – htf) wf = 1 – htf
wm = 1 – htm wm = (1 – kmsm)(1 – htm) wm = (1 – sm)(1 – htm)
B2, B2B2 wf = (1 – sf)(1 – tf) wf = (1 – kfsf)(1 – tf) wf = 1 – tf
wm = 1 – tm wm = (1 – kmsm)(1 – tm) wm = (1 – sm)(1 – tm)

For the sexually antagonistic locus (locus A), there are four parameters: sex-specific selection coefficients, sf and sm, against the deleterious allele for each sex, and dominance coefficients, kf and km (0 < sm, sf < 1; 0 < km, kf < 1). We use three parameters for the B locus: sex-specific selection coefficients, tm and tf, for the cost of the deleterious allele (B2), and a single dominance coefficient (h) with respect to B2, which we assume does not differ between the sexes (0 < tm, tf, h < 1).
