WebMar 1, 2024 · Although the pedigree-based inbreeding coefficient F predicts the expected proportion of an individual's genome that is identical-by-descent (IBD), heterozygosity at genetic markers captures Mendelian sampling variation and thereby provides an estimate of realized IBD. Realized IBD should hence explain more variation in fitness than their … WebAbstract. Waples (2015) has suggested a formula for the Wahlund effect in a case of unequal contribution of samples from genetically different populations that relates Wright's inbreeding coefficient, F IS , and normalized variance in allele frequencies between populations, F ST . I generalize this relationship to a case of multiple alleles and ...
