    Abstract: Genic variation in natural populations of Drosophila simulans was surveyed using allozymic and two-dimensional electrophoretic techniques. Consistent with some previous reports, allozymic heterozygosity appeared lower than in the sibling species D. melanogaster (0.07 vs. 0.16). No variation was detected by two-dimensional electrophoresis of 19 lines scored for 70 abundant proteins. This is consistent with reported reductions in estimates of genic heterozygosity by two-dimensional electrophoresis in D. melanogaster, Mus musculus, and man. Although the amount of intraspecific variation detected in abundant proteins was lower than that detected for allozymes in D. simulans and D. melanogaster, the genetic distances between the sibling species calculated from the two data sets are not significantly different (0.35 and 0.20). The allozyme and two-dimensional electrophoresis data confirmed the impression from other measures of genetic variation (mitochondrial DNA restriction maps and inversion polymorphisms) that D. simulans is substantially less variable than D. melanogaster.

    NULL ALLELE FREQUENCIES AT ALLOZYME LOCI IN NATURAL POPULATIONS OF DROSOPHILA MELANOGASTER

    Abstract: We have sampled a London population of Drosophila melanogaster for null alleles at twenty-five allozyme loci. The same loci and biochemical techniques were used as in our previous survey of a North Carolina population (Voelker et al. 1980). This second survey is completely concordant with the first. No nulls were detected among the five X-linked loci. The mean frequency of nulls at the twenty autosomal loci was 0.0023. Although there is significant interlocus heterogeneity, the two populations appear to have the same frequencies at each locus. This suggests that null alleles at these allozyme loci are in mutation-selection balance, and we estimate the average heterozygous effect of an allozyme null to be 0.0015. Consideration of allozyme null-allele frequencies, the effects of allozyme null alleles on viability and fertility and the generally greater amount of genetic variability at allozyme loci determined by electrophoresis lead us to doubt the validity of generalizing from allozyme data to the whole genome.
