Allelic heterogeneity within allozymes separated by electrophoresis in Drosophila pseudoobscura.

Abstract

Electrophoretic separation of esterase-5 allozymes of D. psuedoobscura in gels of different acrylamide concentrations and in different buffer systems has revealed the existence of 6 different alleles within the most frequent class, esterase-51.00, and 3 alleles in the other most frequent class, esterase-51.07. Two of the alleles affect subunit binding. Esterase-5 allozyme classes based on electrophoresis in 5% acrylamide gels are therefore highly heterogeneous.
