To discover the relation between mitochondrial DNA (mtDNA) polymorphism and the geographic population structure of Drosophila subobscura previously established for other genetic traits, a wide Paleartic survey was carried out. A total of 24 nucleomorphs was observed among 261 isofemale lines assayed by 11 restriction endonucleases with 38 different sites in(More)
Parts of 28S (nuclear) and 12S (mitochondrial) ribosomal RNA of Palearctic, Nearctic and African species of the obscura group have been sequenced by the direct method of sequencing. Rates of nucleotide substitutions in both molecules were compared. The nucleotide divergence is higher in the mitochondrial rRNA. Average distances of species taken in pairwise(More)
