A major challenge for evolutionary biologists is to determine the degree to which natural selection shapes genetic variation in natural populations. Hybridization is common between two species of blue mussel found in the North and Baltic Seas. The differential exchange of genes between the two mussel species, particularly genes encoding enzymes involved in central metabolic pathways, suggests those genes may be under selection and involved in adaptation to low salinity conditions in the Baltic Sea. Tests for selection will be conducted by comparing levels of genetic exchange for these metabolic genes against nonmetabolic and presumably neutral (i.e., not under selection) …
