Fitness and life-history traits of the two major mitochondrial DNA haplotypes of <i>Drosophila subobscura</i>

Mitochondrial DNA restriction site analyses on natural populations of Drosophila subobscura have proved the existence of two common, coexisting haplotypes ( I and II), as well as a set of less frequent ones derived from them. To explain this distribution, experiments to date point practically to all...
