Table 1. The finesses of the karyotypes under different forms of selection.

	Karyotype fitness
	Male				Female
	B	C	D	E	H	I	J	K
Sexually antagonistic selection	1−sm	1−sm dm	1−sm	1	1	1−sf df	1−sf df	1−sf
Heterozygote disadvantage	1	1	1	1	1−sh	1−sh	1	1
Dosage compensation	1	1−0.5sd	1−0.5sd	1−0.5sd	1−0.5sd	1	1−0.5sd	1−sd
Sex chromosome coadaptation	1	1−0.5sc	1−sc	1−sc	1−0.5sc	1−0.5sc	1−0.5sc	1−sc

If more than one form of selection was acting, the values in the corresponding columns were multiplied. The forms of section shown in Figure 4 correspond to the following:

w_{♂ (AU·)}<1≡s_m = 0.1, s_f = 0, d_m = 1; w_♀(Y·)<1≡s_m = 0.1, s_f = 0, d_m = 1; w_♀(FU)<1≡s_h = 0.1.
