WebJul 7, 2024 · How is inbreeding coefficient calculated? In general, for autosomal loci, the inbreeding coefficient for an individual is F = (½)(n1+n2+1), where n 1 and n 2 are the numbers of generations separating the individuals in the consanguineous mating from their common ancestor. (This formula assumes that the common ancestor is not inbred.)
