Table 1.

Selection on mating success, sex, and survival

Factor	β	b	Size of existing fraction, p	Trait variance (existing fraction)	iz
S	.022	−.068	1	.250	<|0.001|
L	1.183	1.180	1	.129	.181
Mm	1.062	1.039	.426	.443	.208
Mf	.724	.662	.422	.154	.031
(Mm −M̄m)2	−.067	.224	.426	.545	−.003
(Mf −M̄m)2	−.460	−.395	.422	.228	.017
R2					.650

Note: The total opportunity for selection is 0.667; the causal model explains 0.434 of this total. The structure of the table follows equation (7b), applied to the case with nonexistent data: the product of the first four numerical columns yields values in the far-right column.
