Inbreeding also increases selection by exposing deleterious recessive mutations, a process called purging that can deplete genetic variation.
WebSome of the methods of estimation of allele frequencies and inbreeding coefficients in a K-allele model are examined. A result that has long been assumed to be true is proved. That …
WebA measure of inbreeding of an individual A is the probability F (A) that both alleles in one locus are derived from the same allele in an ancestor. These two identical alleles that are both derived from a common ancestor are said to be identical by descent. This probability F (A) is called the "coefficient of inbreeding". [42]
