WebJun 17, 2014 · An ancestral allele or an ancestral trait (depending on whether you look at the phenotype or a t the genotype) is the trait/allele that was carried by the common ancestor of the taxon you consider. For example: as you may know the taxon Reptilia includes lizards, snakes, turtles, birds, mammals and some other lineages.

The expected allele frequency spectrum may be calculated using either a coalescent or diffusion approach. The demographic history of a population and natural selection affect allele frequency dynamics, and these effects are reflected in the shape of the allele frequency spectrum. For the simple case of selective neutral alleles segregating in a population that has reached demographic equilibrium (that is, without recent population size changes or gene flow), the expected allele fre… WebMay 28, 2024 · The site frequency spectrum (SFS) is a statistic that summarizes the distribution of derived allele frequencies in a sample of DNA sequences.
