Using 16 microsatellite loci, we estimated the degree of inbreeding of each pair's progeny in three ways: (1) identity (I) or the expected homozygosity of the progeny based on their parents' genotypes estimated using the IDENTIX program, (2) a moment-based estimator of the pair-wise coefficient of relatedness (W) of each parental pair estimated using the MER program of Wang, and (3) a modified estimator of the pair-wise coefficient of relatedness (K) designed specifically to accommodate null alleles, which were common in the Dabob Bay population and estimated using the ML-RELATE by Kalinowski.
