  • Title: Adjusting for selection on synonymous sites in estimates of evolutionary distance.
    Author: Hirsh AE, Fraser HB, Wall DP.
    Journal: Mol Biol Evol; 2005 Jan; 22(1):174-7. PubMed ID: 15371530.
    Abstract:
    Evolution at silent sites is often used to estimate the pace of selectively neutral processes or to infer differences in divergence times of genes. However, silent sites are subject to selection in favor of preferred codons, and the strength of such selection varies dramatically across genes. Here, we use the relationship between codon bias and synonymous divergence observed in four species of the genus Saccharomyces to provide a simple correction for selection on silent sites.
