Four stocks derived from aberrant segregation of R-locus genes in male progeny following incompatible crosses in Mormoniella have shown characteristics suggesting that genes found on added chromosomal fragments in these stocks have separated from each other. In most cases, this separation was associated with elevated temperatures at the time of and subsequent to fertilization. Data also suggest that the R-locus genes involved are adjacent to a centromere, with the O factor being proximal thereto.
在莫氏果蝇中，不亲和杂交后雄性子代中R位点基因异常分离产生的四个品系表现出的特征表明，这些品系中附加染色体片段上发现的基因已彼此分离。在大多数情况下，这种分离与受精时及受精后的高温有关。数据还表明，所涉及的R位点基因与着丝粒相邻，O因子位于其近端。
