A high incidence of selection on physiologically important genes in the three-spined stickleback, Gasterosteus aculeatus.

Abstract excerpt

Genome scan approaches to detect footprints of directional selection in the genomes of wild animal and plant populations have become popular tools to study local adaptation and speciation at the molecular level. Most studies thus far have used random molecular markers and found footprints of directional selection at, on average, 5% (range: 1-15%) of the examined loci. We focused on physiologically important genes...
