Description
Summary:Genetic relationships among Mytilus populations throughout the North Atlantic region, including the Mediterranean and the Baltic Sea, were studied using enzyme electrophoresis. Three distinct groups of populations, each of a remarkably wide distribution, can be recognised on the basis of their multilocus allelic composition: (1) M. galloprovincialis L. of the Mediterranean and western Europe; (2) a genetically distinct form of M. edulis Lmk. from both the Baltic Sea and some localities in the Canadian Maritime Provinces (here provisionally termed the "trossulus type mussel"); and (3) the traditional "Atlantic" M. edulis populations of northwestern European coasts and most of eastern North America.
