WebJan 17, 2024 · Variant data can also be used to estimate the coefficient of inbreeding (F), which is a metric that describes the distribution of variants in a population. According to the Hardy–Weinberg (HW) principle, F = 0 for a given variant indicates HW equilibrium. By this measure, a fully inbred strain has an inbreeding coefficient of F = 1.0 (100%). WebMar 1, 2010 · The inbreeding effective number is infinite (since there is no chance for two individuals to share a common ancestor) while the variance number is ∼2 Nt.
