Inbreeding coefficient equation
In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. These influences include genetic drift, mate choice, assortative mating, natural selection, sexual se… WebMay 1, 2024 · Range of values and interpretation of the genomic inbreeding coefficients. The inbreeding coefficients investigated differ in the range of values that they can contain and, with the exception of \({F}_{NEJ}\), their ranges depend on the allele frequency in the base population \({p}_{(0)}\).Coefficient \({F}_{NEJ}\) ranges from 0 to 1 because it is the …

WebThe relation between the frequencies of expected versus observed heterozygotes allows us to determine the inbreeding coefficient, F = (He - Ho)/He (subscripts e and o mean expected and observed, respectively). One effect of inbreeding is to increase the frequency of homozygotes (and thus, necessarily, decrease the frequency of heterozygotes).
