TABLE 1.

Theoretical load (L), observed load $\left(\hat{L}\right)$, and mean fitness $\left(\hat{w}\right)$ in samples of 100 individuals

	$\hat{p}$
	0.05	0.1	0.2	0.4	0.5
s1	0.038	0.018	0.008	0.003	0.002
L	1.6	1.5	1.2	0.82	0.65
$\left(\hat{L}\right)$	0.075	0.093	0.09	0.069	0.057
$\left(\hat{w}\right)$	0.39	0.41	0.45	0.55	0.61

The column heading $\hat{p}$ and the row heading s₁ refer to the equation of overdominance outlined in the text. In each case, s₂ = 0.002. The value of s₁ was chosen to give the equilibrium allele frequency indicated in the table.
