The frequency distribution of nucleotide variation in Drosophila simulans.

Molecular biology and evolution - 1 Jul 2001

Begun D J

Abstract excerpt

Patterns of codon bias in Drosophila suggest that silent mutations can be classified into two types: unpreferred (slightly deleterious) and preferred (slightly beneficial). Results of previous analyses of polymorphism and divergence in Drosophila simulans were interpreted as supporting a mutation-selection-drift model in which slightly deleterious, silent mutants make significantly greater contributions to...
