| mitochondrial dna haplotype frequencies in natural and experimental populations of drosophila subobscura. | the evolution of drosophila subobscura mitochondrial dna has been studied in experimental populations, founded with flies from a natural population from esporles (majorca, balearic islands, spain). this population, like other european ones, is characterized by the presence of two very common (>96%) mitochondrial haplotypes (called i and ii) and rare and endemic haplotypes that appear at very low frequencies. there is no statistical evidence of positive darwinian selection acting on the mitochond ... | 1998 | 9649527 |
