WebThe ratio of non-synonymous to synonymous substitutions (dN/dS) is a useful measure of the strength and mode of natural selection acting on protein-coding genes. It is widely used to study patterns of selection on protein genes on a genomic scale-from the small … WebMar 8, 2024 · In this paper, we develop a new criterion, called Δ-dN / dS , for positive selection testing by introducing an index H , which is a relative measure of rate variation among sites. Under the context of strong purifying selection at some amino acid sites, our model predicts dN / dS =1- H for the neutral evolution, dN / dS <1- H for the nearly …
