Abstract
Twenty different natural populations of Drosophila melanogaster were sampled to determine the frequencies of inversions. Based on their frequencies and geographical distributions, the inversions could be classified as follows: (1) Common cosmopolitan inversions that are present in many populations in frequencies exceeding five percent and that may exhibit frequency clines over large geographical regions; (2) Rare cosmopolitan inversions that occur throughout the species range but usually at frequencies below five percent and that may be absent in many populations; (3) Recurrent endemic inversions that are found in several adjacent populations in frequencies usually not exceeding one or two percent; and (4) Unique endemic inversions that are found only among the progeny of a single individual and that may represent one aspect of the syndrome termed "hybrid dysgenesis". Four common cosmopolitan inversions that exhibit highly significant clines in populations in the eastern United States are In(2L)t, In(2R)NS, In(3L)P and In(3R)P.
