title: Cytogenetic mapping of marker genes on the chromosome elements C and E of Drosophila pseudoobscura and D. subobscura.
abstract: Enzyme loci, visible marker genes and lambda-cloned DNA-sequences from a D. miranda library were mapped cytologically on the chromosome elements C and E of D. pseudoobscura and D. subobscura. New data are incorporated into the linkage maps of the two species. Homologous segments can now be localized in the polytene chromosomes with these markers. A comparison of the chromosome elements E of D. melanogaster and D. subobscura shows 12 conserved subsections which have been rearranged by paracentric inversions in the evolution of the two lineages.
