Rhynchosciara americana genomic DNA when digested with EcoR1 or BamH1 presents visible fragments suggestive of repetitive sequences after fractionation on EtBr stained agarose gels. The cloning and molecular analysis of some of these fragments showed a highly polymorphic family of repetitive sequences. These were mapped by in situ hybridization to telomeres and some heterochromatic regions on polytene chromosomes.
