Abstract
Genetic variability and the distribution of this variability was examined in two size classes (1 to 2 mm and 9 to 10 cm valves) of the mussel Mytilus californianus. Marked homozygote excess was observed at two polymorphic loci (Lap and Pgi), and the excess was far greater in juveniles than in adults. It is suggested that both the homozygote excess and the significantly greater excess in juveniles are due to subdivision in the reproductive population.
