Hence … WebMar 1, 2024 · Furthermore, Stoffel et al. explicitly redefined the inbreeding coefficient as used in, for example, Szulkin et al. , to represent a variable that explains all the variance in heterozygosity. This results in a version of g 2 that captures variation in realized IBD rather than variation in F .
WebDec 2, 2024 · The level of inbreeding can be estimated using pedigrees, which were commonly used to determine the coefficient of inbreeding (F p) within individuals and breeds ; however, unless calculations include the complete pedigree [4, 5], F p may underrepresent the actual inbreeding by 5–10 fold [6,7,8]. More recently, measurement of …
