Differences between observed and simulated means of genetic similarity of mates

	Phm (prob. of producing a homozygous offspring)
	All pairs in both years	Stable pairs in both years	2003	2004
Pairs (P)	92	58	74	72
Adults (N)	348	348	241	289
All loci	0.184	0.182	0.181	0.184
	0.199	0.199	0.196	0.201
	0.016	0.029	0.021	0.018
Without OHW loci	0.172	0.171	0.162	0.174
	0.189	0.189	0.184	0.191
	0.026	0.048	0.005	0.043

Distributions of Phm estimated by performing 10,000 random repairings of P pairs among the N possible adults and calculating the simulated mean genetic similarity between mates. For each estimate, the first provides the observed mean genetic similarity between mates for the population and the second line reports the simulated mean, the last line is the p-value calculated as the proportion of bootstraps having a mean genetic similarity between mates lower than the observed mean. Significant p-values are in bold. The first column contains the results for both years combined (each pair counted only once), the second contains the results for all years combined using only pairs breeding together in both years (with again each pair counted only once).
