F _G, inbreeding coefficient estimated as the probability of belonging to any of the HBD classes averaged over the whole genome; F _HOM, inbreeding coefficient based on the proportion of homozygous SNPs; F _ExHOM, excess homozygosity estimator; F _ROH, inbreeding coefficient estimated as the proportion of the genome captured by ROH; F _GRM1, inbreeding coefficient based on the diagonal elements of the genomic relationship matrix (dividing all SNP contributions by the same denominator); F _GRM2, inbreeding coefficient based on the diagonal elements of the genomic relationship matrix (dividing each SNP contribution by its own weight 2f _i (1 − f _i), f _i being the frequency of allele i); F _UNI, inbreeding coefficient based on the correlation between uniting gametes; F _PED, inbreeding coefficient estimated from pedigree data
