WebJul 20, 2024 · Sibling pair genetic relatedness. Genetic relatedness among sibling pairs was computed based on maternal report data collected earlier in the study. Values of relatedness were assigned based on assumed pedigree relationships (monozygotic twins = 1.0; dizygotic twins or full siblings = 0.50; half siblings = 0.25; nonbiological siblings = 0.0). The 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 … See more The coefficient of relationship ($${\displaystyle r}$$) between two individuals B and C is obtained by a summation of coefficients calculated for every line by which they are connected to their See more The coefficient of relationship is sometimes used to express degrees of kinship in numeric terms in human genealogy See more • Evolutionary biology portal • Accidental incest • Effective population size • F-statistics • Genetic distance • Genetic diversity See more 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.
