Inbreeding coefficient practice problems
WebThe inbreeding coefficient is a measure of the proportion by which the heterozygosity of an individual is reduced by inbreeding. Although Wright derived his algorithm by using correlation coefficients, this derivation has been largely replaced by using the concept of “identity by descent (IBD)”. WebPop. 2. Excess of 15.5 homozygotes: some inbreeding Pop. 3. Deficiency of 45 homozygotes: outbred or experiencing a Wahlund effect (isolate breaking). Step 3. Calculate the local observed heterozygosities of each subpopulation (we will call them H obs s, where the s subscript refers to the s th of n populations -- 3 in this example).
