Supplemental Table 2: Measures of genetic diversity in the filial generation of 23 stands of white spruce in Northern Ontario. Stand size, number of reproductive trees in a stand: Sample size, number of genotypes (embryos) sampled; He, mean expected heterozygosity; Ho, mean observed heterozygosity; f, multilocus inbreeding coefficient (Weir and Cockerham, 1984); A, mean number of alleles locus; Ae, number of effective alleles; LGP, latent genetic potential; GA(O), genotypic additivity (observed); GA(E), genotypic additivity (expected); AR, allelic richness; H, gene diversity; Fis, inbreeding coefficent. All trees were sampled in small stands and 6 trees per stand were sampled in large and medium-sized stands.
