Phosphoglucomutase polymorphism in the oriental fruit fly, Dacus dorsalis (Diptera, Tephritidae) from Peninsular
Abstract:
Seven natural populations of Dacus dorsalis were analysed for phosphoglucomutase by means of horizontal starch-gel electrophoresis. The electrophoretic phenotypes were governed by four codominant Pgm alleles. The commonest allele in all the seven population samples was PgmB which encoded an electrophoretic band with intermediate mobility. The distributions of PGM phenotype were in accordance with Hardy-Weinberg expectations. There was geographic variation in the distribution of Pgm alleles.
