WebAverage expected heterozygosity (H e) (Nei’s genetic diversity [D]) Where, h j = heterozygosity per locus p and q = allele frequencies H = average heterozygosity for several loci L = total number of loci • The average expected heterozygosity is ca lculated by substracting from 1 the expected frequencies of homozygotes in a locus. WebThe most obvious effects of inbreeding are poorer reproductive efficiency including higher mortality rates, lower growth rates and a higher frequency of hereditary abnormalities. This has been shown by numerous studies with cattle, horses, sheep, swine …

WebApr 14, 2024 · Embark can assist breeders with the Pair Predictor tool located in the breeder dashboard. A breeder can select two Embark-tested dogs and it will provide the expected COI for that match. It compares potential sires and lets the breeder choose the sire with the lowest expected COI. Pair Predictor also assesses predicted health condition risks.

WebDec 5, 2024 · Inbreeding can alter the gene pool. This is because it predisposes to homozygosity. Potentially harmful recessive alleles — invisible in the parents — become exposed to the forces of natural selection in the children. Figure 18.6.1: Assortative mating.
