GENETICS OF GLOSSINA MORSITANS MORSITANS (DIPTERA: GLOSSINIDAE): I. ELECTROPHORETIC BANDING PATTERNS OF XANTHINE OXIDASE AND ALDEHYDE OXIDASE

Abstract

AbstractPolyacrylamide gel (6%) electrophoresis (at pH 8.2) of the thoraces of adult Glossina morsitans morsitans Westwood revealed three xanthine oxidase (XO) phenotypes and six aldehyde oxidase (AO) phenotypes. Each enzyme was postulated to be under the control of a single locus, XO with two alleles and AO with three alleles. Gene frequencies were in Hardy-Weinberg equilibrium for both loci in two laboratory populations. Breeding experiments provided direct evidence for single locus control of each enzyme. No significant differences in phenotype frequencies were observed between the colony maintained at the University of Alberta, Canada and the parent colony at the University of Bristol, England. A colony of highly inbred flies from the University of Bristol had only one phenotype of AO and of XO.
