Web15 nov. 2024 · The kinship coefficient quantifies the genetic similarity between two individuals by the probability that randomly sampled homologous genes from the two individuals are identical by descent (IBD) given their pedigree‐based relationship. Inbreeding is the probability that the two genes at a locus are IBD. The kinship coefficient is a simple measure of relatedness, defined as the probability that a pair of randomly sampled homologous alleles are identical by descent. More simply, it is the probability that an allele selected randomly from an individual, i, and an allele selected at the same autosomal … Meer weergeven The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals.
