WebApr 2, 2024 · The inbreeding coefficient (typically denoted by the symbol F) is the probability that an inbred individual has two alleles at a given locus that are identical because of inheritance from a common ancestor. F is thus the probability of identity by descent. 3.1.3.1 How to Compute the Inbreeding Coefficient
