Inbreeding allele frequency

The measures FIS, FST, and FIT are related to the amounts of heterozygosity at various levels of population structure. Together, they are called F-statistics, and are derived from F, the inbreeding coefficient. In a simple two-allele system with inbreeding, the genotypic frequencies are: The value for is found by solving the equation for using heterozygotes in the above inbred population. This becomes one minus the observed frequency of heterozygotes in a population div… WebInbreeding does not alter allele frequencies directly but affects disease incidence through a separate mechanism.
