Abstract

MACRAE and ANDERSON observed a large frequency change of mitochondrial DNA (mtDNA) haplotypes in a population initiated with two allopathic strains of Drosophila pseudoobscura, BogER from Colombia and AH162 from California. They concluded that mtDNA haplotypes in D. pseudoobscura are not always selectively neutral. NIGRO and PROUT suggested, however, that a maternally transmitted incompatibility system, similar to the one they observed in two strains of D. simulans from Italy, could account for the observed mtDNA frequency changes. SINGH and HALE postulated that a mating preference between the strains BogER and AH162 in MACRAE and ANDERSON's experiment, in the form of negative assortative mating, could also account for the mtDNA frequency changes. We report two experiments designed to test the hypotheses: that a maternally transmitted cytoplasmic incompatibility system exists between D. pseudoobscura strains BogER and AH162; and, that BogER females male preferentially with AH162 males. Our results do not support either hypothesis.
