Nonsynonymous substitution in abalone sperm fertilization genes exceeds substitution in introns and mitochondrial DNA.

Proceedings of the National Academy of Sciences of the United States of America - 1 Sept 1998

Metz E C, Robles-Sikisaka R, Vacquier V D

Abstract excerpt

Strong positive Darwinian selection acts on two sperm fertilization proteins, lysin and 18-kDa protein, from abalone (Haliotis). To understand the phylogenetic context for this dramatic molecular evolution, we obtained sequences of mitochondrial cytochrome c oxidase subunit I (mtCOI), and genomic...
