dc.description.abstract Two endemic sympatrically occurring Hawaiian Drosophila species found in closely adjacent Kipuka Ki and Kipuka Puaulu on the island of Hawaii have been examined at about 20 electrophoretic loci for the extent of their genetic variability. In D. mimica, 47.6% of such loci were polymorphic, with individuals polymorphic at ~ 19% of their loci on the average. For D. engyochracea, these figures are 30% and = 12%. Levels of variability appear to be higher in Kipuka Ki populations of both species. In addition, higher numbers of alleles are observed in D. engyochracea than are expected from predictions based on the neutral gene hypothesis. The evolutionary advantages of such high levels of variability are discussed and the suggestion is made that the genetic variability in these species serves some adaptive function.
