A Dissertation Submitted to the Faculty of Science of the University of
the Witwatersrand, Johannesburg, in fulfilment of the requirements for
the Degree of Master of Science. / Impala are an ancient and successful specdes whose biogeography differs
from other bovids. A detailed electrophoretic investigation of genetic
variability within and between subpopulations found six polymorphic loci,
CK-C"', GPl"', MPr\ PEP-Jr, PGM-2'" and PROT-2'" in a sample of 464 impala
collected from 10 localities in southern Africa. Average gene diversity
was 0,047. Between-population gene diversity was normal for bovid
species. Allele frequency differences and genetic distances revealed low
levels of subdivision into three broad regions. Wright's FST (0,035)
revealed a significant yet low level of population subdivision. The distributions
of single-locus heterozygosities and allele frequencies were
significantly different to those predicted during mutation-drift equi
librium, indicating that non-equilibrium conditions may prevail and that
the population may be recovering from a recent bottleneck. / AC 2018
