Title: Length polymorphisms, restriction site variation, and maternal inheritance of mitochondrial DNA of Drosophila melanogaster
Abstract: We have studied the mitochondrial DNA in three wild type laboratory strains of Drosophila melanogaster, ry+5 and two Oregon R-substrains, called here R and E. Lengths of the restriction bands for EcoRI, BglII, HpaII, MspI, HaeIII, and HindIII were compared. The number of restriction sites was identical in all strains, with the exception of an extra HaeIII site in ry+5. Careful comparison of restriction fragment lengths showed that bands containing the AT-rich region were different in length among all strains. The laboratory strains, ry+5, proved to be a mixture of strains carrying different mtDNAs; these separated into substrains G1 and G2 in the progeny of single pair matings. Adult progeny of reciprocal crosses of G1 and R were analyzed by HaeIII restriction digestion. The results demonstrated maternal inheritance for both the extra restriction site and band containing the AT-rich region.
