Genetic differences among natural populations of the blue mussel (Mytilus edulis) appear to have implications for commercial exploitation of the species. Growth and mortality patterns in transplanted versus resident wild stocks presented here verify

In animals, mitochondrial DNA (mtDNA) inheritance is predominantly maternal. In a few cases incidental transmission of paternal mtDNA was observed and estimated to account for only 10(-4)-10(-3) of an individual's mtDNA content. In contrast, biparent

High-elevation valleys in dry areas of the Himalayas are among the most extreme, yet least explored environments on Earth. These barren, rocky valleys are subjected to year-round temperature fluctuations across the freezing point and very low availab

To investigate the influence of genetics and environment on the growth of Mytilus edulis at low temperatures, we transplanted juveniles from 11 stocks to 10 sites along the coast of Nova Scotia, Canada. For each stock at each site, the mean change in

Juveniles of the blue mussel Mytilus edulis that had resulted from a large number of pair matings were examined at six polymorphic enzyme loci. In four loci, the overall number of heterozygotes was significantly less than expected from the parental g

Comparative production estimates of selected species may provide indices of environmental quality, but so far there is little information on the extent to which production responses are mediated by genotypes. This study used a single source stock of

Shell length and electrophoretic heterozygosity at six enzyme loci were scored in juveniles of 30 hatchery-grown families and in adults of 10 field-grown families of the blue mussel Mytilus edulis. A total of 4 809 offspring were scored. We found no

Genetic differences among Mytilus edulis populations from four localities in Atlantic Canada were examined using electrophoretic techniques. On the basis of allele frequency distributions at four loci (LAP-1, PEPTIDASE-2, PGI, PGM), the localities fe
