Webb26 apr. 2024 · To ensure data quality, quality control (QC) was performed across the six goat populations by removing any SNPs with call rate <95%, MAF <0.05 and Hardy–Weinberg equilibrium (HWE) (p < 10 −5) using PLINK v. 1.07 . Moreover, samples with more than 10% missing genotypes were removed from the data set. Webb14 maj 2024 · The Hardy-Weinberg law is named in honor of the two men who first realized the significance of the binomial expansion to population genetics and hence to evolution. Evolution involves changes in the gene pool. A population in Hardy-Weinberg equilibrium shows no change.

WebbThe Hardy-Weinberg equation can be used to test whether evolution is occurring in a population-This means that at least one of the 5 factors must be at work for evolution to occur-It is also used to determine the percentage of a population carrying a specific allele Concept 23.3: Natural selection, genetic drift, and gene flow can alter allele frequencies … WebbWhen a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations.
