The categorization of naturally occurring inversions in Drosophila melanogaster made by Mettler et al. (1977) was re-examined through compilation of recent data from the world-wide investigations. Categorization was changed into 5 classes by adding a new class: Common cosmopolitan, Rare cosmopolitan, Quasi cosmopolitan, Endemic and Unique. Modifications were also proposed: (1) The Rare cosmopolitans were limited to the 3 inversions, In(3L)M, In(3R)C and In(3R)Mo, instead of 8 inversions originally included. (2) Ambiguity between Endemic and Unique was noted and discussed. Data were presented to show that repeated surveys of the usual scale in a natural population indeed detected Endemic inversions which otherwise would have been classified as Unique inversions. More recent data on Japanese natural populations were finally presented. The Common cosmopolitans but not the Rare and Quasi cosmopolitans clearly showed high frequencies in the south.
通过汇总来自全球范围调查的最新数据，重新审视了梅特勒等人（1977年）对黑腹果蝇自然发生倒位的分类。通过增加一个新类别，分类变为五类：常见世界性、稀有世界性、准世界性、地方性和独特性。还提出了一些修改建议：（1）稀有世界性倒位仅限于3种倒位，即In(3L)M、In(3R)C和In(3R)Mo，而不是原来包含的8种倒位。（2）指出并讨论了地方性和独特性之间的模糊性。提供的数据表明，在自然种群中进行常规规模的重复调查确实检测到了地方性倒位，否则这些倒位会被归类为独特倒位。最后展示了关于日本自然种群的最新数据。常见世界性倒位在南方明显呈现高频率，而稀有和准世界性倒位则不然。
