Abstract
ELECTROPHORESIS detects only about one third of the genetic variation present in a natural population, despite its wide application1. A combination of electrophoretic and heat denaturation techniques has revealed considerable molecular variation within single electrophoretic classes of enzymes. For example, Bernstein et al.2 have found 1.74 more alleles at the xanthine dehydrogenase locus in the Drosophila virilis group than had been detected by electrophoresis alone. Further such evidence3–11 has concentrated on species of Drosophila. I report here a study of the marine mussel Guekensia demissa (formerly Modiolus demissus) which shows that in two geographically separated populations experiencing different temperature regimes, there is an apparent correlation between the distribution of thermosensitive alleles at the phosphoglucomutase (Pgm) locus and environmental temperature.
