Abstract
Allozyme frequency data from five Greek wild sympatric populations of Drosophila melanogaster and D. simulans along a North-South gradient were analyzed for genotype-environment relationships. The regression coefficient of genetic distance on geographic distance indicates that there is a significant relationship between these parameters for D. melanogaster only. Highly significant differences in specific alleles at certain loci were found between the various local populations studied. The changes in αGpdh Fof D. melanogaster and Est-6 Fof D. simulans exhibited clinal patterns in allele frequencies. In addition, analysis of D. melanogaster αGpdh Fand Adh Fallele frequencies shows that the Greek data do not have regression coefficients (regressing allele frequency on degrees North of latitude) of the same sign as East-and West-Coast United-States populations. These contradictory data are discussed in relation to what is known about the maintenance of the Adh and αGpdh polymorphisms.
