dominance

Kenney-Hunt JP & Cheverud JM 2009 Differential dominance of pleiotropic loci for mouse skeletal traits. Evolution 63:1845-1851. "differential dominance" describes the situation in which the dominance effects at a pleiotropic locus vary bet…

deleterious mutation

Glémin S 2003 How are deleterious mutations purged? Drift versus nonrandom mating. Evolution 57:2678-2687. the higher |Δx|, the more deleterious alleles should be eliminated purging by drift is thus possible if |Δx|drift ≥ |Δx|∞ |Δx|drift …
