Inbreeding and relatedness coefficients: what do they measure?

摘要: This paper reviews and discusses what is known about the relationship between identity in state, allele frequency, inbreeding coefficients, by descent various uses of these terms. Generic definitions coefficients are given, as ratios differences probabilities state. Then some their properties derived from an assumption terms distributions coalescence times different genes. These give approximate measurement how much higher probability recent for pair genes relative to another pair. Such a measure general not equivalent descent; rather, it approximates ratio descent. results contrasted with other formulas relating identity, coefficients. Additional assumptions necessary obtain most them, always correct, example when there localized dispersal. Therefore, based on such well-formulated. By contrast, generic both well-formulated more broadly applicable.
