Increased genetic diversity in mitochondrial genes is correlated with the evolution of parasitism in the Hymenoptera.

Abstract excerpt

A higher AT content and rate of mtDNA sequence divergence was found in parasitic wasps (Apocrita) compared with nonparasitic wasps (Symphyta). The compositional bias was reflected in extreme codon bias for a cytochrome oxidase I protein coding gene fragment as well as in the types of amino acid substitutions that have occurred during the evolution of this gene fragment. In some instances, compositional bias...
