The genetic structure of Drosophila subobscura population from the Lazar’s
River Canyon (Serbia) was studied with respect to restriction site
polymorphism of mitochondrial DNA and chromosomal inversion polymorphism. The
aim was to shed more light on the role of cytonuclear interactions in shaping
mitochondrial DNA variability in this species. Similar to other populations
of D. subobscura two main haplotypes (I and II) were found, as well as less
common ones that appeared at very low frequencies. The frequency distribution
of haplotypes did not depart from neutrality. We did not find statistically
significant linkage disequilibrium between the haplotypes belonging to
haplogroups I and II and any of the chromosomal arrangements. However, when
we compared the data in hereby analyzed population and two previously
analyzed populations we observed that haplotype I is more frequent in
populations where standard inversion arrangements are less frequent. Pattern
of the observed mitochondrial variability could be influenced either directly
by environmental variability or through environmentally specific cytonuclear
coadaptation.
