Letter to the Editor Population Genetics of Silent and Replacement Variation in Drosophila simulans and D. melunogaster: X/Autosome Differences?


Drosophila simulans and D. melanogaster are closely related, cosmopolitan, human commensals. Despite these similarities, population genetic data had suggested that melanogaster was much less heterozygous than simulans for restriction site variation (Aquadro, Lado, and Noon 1988; Aquadro 1989), although allozyme heterozygosities were roughly the same… (More)
