Table 1.

Observed and estimated AIS probability, and estimated parent-based coancestries among actual nonsibs (NS), actual half-sibs (HS), actual full-sibs (FS) and all pairs of sampled progeny from the noninbred and inbred parental populations under monogamy with N = 10 parents or polygyny with N_m = 5 male and N_f = 20 female parents, for the case of L = 15 high-polymorphic marker loci and the sample size of n = 100.

		AIS probability		Estimated parent-based coancestry among
Breeding system	Population	Observed	Estimated	Actual NS	Actual HS	Actual FS	All pairs
Monogamy	Noninbred	0.3587	0.3571	0.0045	–	0.2552	0.0546
	Inbred	0.3565	0.3366	0.0346	–	0.2651	0.0806
Polygyny	Noninbred	0.2967	0.2972	0.0008	0.1259	0.2503	0.0370
	Inbred	0.2981	0.2830	0.0237	0.1418	0.2592	0.0579

The AIS probability is the average over 5000 replicates and 15 marker loci, and the coancestry is the average over 5000 replicates.
