Abstract

The genetic structure of seven populations of Drosophila subobscura from different locations on Majorca and Minorca (Balearic Islands, Spain) was studied using two types of markers: allozyme and mitochondrial DNA restrictionanalyses. Both markers showed congruent results. In the allozyme data, when the Acph-1 locus was excluded from the joint F-ST statistics, only three out of 21 comparisons were statistically significant, lending support to the hypothesis of low genetic differentiation. The mtDNA restriction analysesshowed two haplotypes at a high frequency (more than 40% each), irrespective of the location considered, and a number of endemic haplotypes at very low frequencies (not higher than 2% each). The analyses of the genetic structure yielded a pattern similar to the allozymes. The cytonuclear disequilibrium analyses showed the difficulty of detecting cytonuclear associations in natural populations because they are mainly transient.
