Webof novel variants in a two-locus model and the equilibrium effects of interference with multiple loci and reversible mutation. We find that weak selection Hill-Robertson (wsHR) interference can considerably reduce adaptation, e.g., codon bias, and, to a lesser extent, levels of polymorphism, particularly in regions of low recombination. WebDec 1, 2008 · This process is known as clonal interference (Gerrish and Lenski 1998; Gerrish 2001; Wilke 2004). The same process also operates in a sexual population, where it is referred to as the Hill–Robertson effect, but is mitigated because the two competing mutations can potentially recombine onto the same genome and fix together (Hill and …
