WebThis value can be interpreted as the “average heterozygosity of all genes in an individual” or as “the probability of observing a heterozygote at a particular locus.” Subpopulation heterozygosity ( \(H_S\) ): This is the rate of heterozygosity expected at a particular sampling sub-population (or what I refer to in this text as a locale). WebFeb 28, 2024 · The value of expected heterozygosity ( H e = 0.655) was higher than that of observed heterozygosity ( H o = 0.317), which indicated an excess of homozygosity within populations, which could be due to inbreeding. The gene flow among populations was high ( Nm = 1.245) while the genetic differentiation among populations was low ( Fst = 0.169).

WebOct 9, 2024 · The expected heterozygosity is a measure of genetic diversity, giving the probability that two alleles randomly drawn from a population differ in type. Definition 1 The expected heterozygosity in a population for a given locus with J distinct alleles is defined as H = 1- \sum _ {j=1}^J p_j^2, where p_j is the frequency of allelic type j.

WebFeb 5, 2024 · Heterozygosity and Polymorphism Information Content. The heterozygosity of a marker is the likelihood of an individual being heterozygous at the marker site and depends on the number of alleles and their frequency in the population.
