WebThe coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy.A coefficient of … WebHO: observed heterozygosity, FIS: inbreeding coefficient, G-W.: Garza-Williamson index. * and **: Significant deviation from HWE after application of Narum correction (P<0.05).

WebThe INBREEDING COEFFICIENT, F,is used to gauge the strength of inbreeding. F= probability that two alleles in an individual areidentical by descent(IBD). Fstands for fixation index, because of the increase in homozygosity, or fixation, that results from inbreeding.
