Abstract
Pgm allele frequencies of 383 individuals were determined in a sample ofDrosophila melanogaster from three laboratory Sardinian populations, using the techniques of standard electrophoresis, heat denaturation, and isoelectric focusing. The analysis of the progeny obtained from informative crosses showed that the isoelectric focusing patterns segregate in a Mendelian way. ThePgm 1.00 andPgm 0.70 electrophoretic alleles displayed different isoelectric points, whereas thePgm 1.00,tr andPgm 1.00,ts isoelectrophoretic alleles could not be differentiated when tested by isoelectric focusing. Moreover, thePgm 0.70,ts allele was split into two classes, with isoelectric points ofpH 6.4 andpH 6.6.This publication has 17 references indexed in Scilit:
