Recombination rates vary within and between species. A gene that causes a difference in rate and pattern of crossing over between two species of Drosophila has been identified in a new study, and shown to evolve under natural selection.
重组率在物种内和物种间存在差异。在一项新的研究中，鉴定出一个导致果蝇两个物种间交叉互换率和模式差异的基因，并证实该基因在自然选择下进化。
