我们尝试将Y染色体导入到果蝇的三个近缘种之间:拟果蝇、果蝇和毛果蝇。将4条D·sechellia Y染色体导入到D·sechellia中而不损失育性,而4条相互导入(D·simans Y导入D·sechellia)均导致不育。拟态石斑菌和毛状石斑菌(各四株)的反Y导入也会导致不育。与雄性拟青蛙相比,在拟青蛙背景中具有D-sechellia Y染色体的雄性繁殖力较低,但只有在与处女雌性进行多次交配后才能繁殖。与纯物种雄性相比,这些雄性在精子置换和/或记忆能力上也处于劣势。然而,在雌性选择测试中,这两个不同的Y基因型雄性在生存能力、寿命和交配成功率方面具有可比性。我们还利用我们的结果估计了与X连锁基因相互作用产生杂交雄性不育的常染色体座位的有效数量。
We attempted to introgress Y chromosomes between three sibling species of Drosophila: D. simulans, D. sechellia and D. mauritiana. Four D. sechellia Y chromosomes were introgressed into D. simulans without loss of fertility whereas the four reciprocal introgressions (D. simulans Y introgressed into D sechellia) all result in sterility. Both reciprocal Y introgressions of D. simulans and D. mauritiana (four of each) also result in sterility. Compared with D. simulans males, the males with the D. sechellia Y chromosome in D. simulans background had lower productivity but only after multiple matings with virgin females. These males also were inferior compared with pure species males in sperm displacement and/or remating ability. The two different Y genotype males, however, were comparable in viability, longevity and mating success in female choice tests. We also use our results to estimate the effective number of autosomal loci interacting with X-linked genes to produce hybrid male sterility.
