当从毛里求斯果蝇渗入模拟果蝇时,X染色体的至少六个区域可以引起雄性不育。在这篇文章中,我们提出了其他健身效果所造成的两个X-连锁区域,含有杂种雄性不育因子的结果。在这两个区域中,与缺乏不育因子的基因渗入的杂合雌性相比,对于具有这样的不育因子的基因渗入的杂合雌性产生实质上更少的后代。因此,杂种雄性不育因子或其附近的其他基因对雌性生产力具有实质性的影响。相反,杂种雄性不育因素对两性的相对生活力几乎没有影响。这些研究结果的进化意义进行了讨论。
At least six regions of the X chromosome can cause male sterility when introgressed from Drosophila mauritiana into Drosophila simulans. In this article, we present the results of the other fitness effects caused by two X-linked regions that contain hybrid male sterility factors. In both regions, females that are heterozygous for an introgression with such a sterility factor produce substantially-fewer offspring than females heterozygous for an introgression that lacks the sterility factor. Thus, the hybrid male sterility factors, or other genes nearby, have substantial effects on female productivity. In contrast, hybrid male sterility factors have little or no effect on the relative viabilities of either sex. The evolutionary implications of these findings are discussed.
