The behaviour of two "meiotic drive" systems, Segregation-Distorter (SD) and the sex chromosome sc(4)sc(8) has been examined in the same meiocyte. It has been found that the two systems interact in a specific way. When the distorting effects of SD and sc(4)sc(8) are against each other, there is no detectable interaction. Each system is apparently oblivious to the presence of the other, gametes being produced according to independence expectations. However when the affected chromosomes are at the same meiotic pole an interaction occurs; the survival probability of the gamete containing both distorted chromosomal products is increased, rather than being decreased by the combined action of two systems.
在同一个减数分裂细胞中，对两种“减数分裂驱动”系统，即分离畸变（SD）和性染色体sc(4)sc(8)的行为进行了研究。已发现这两种系统以一种特定方式相互作用。当SD和sc(4)sc(8)的畸变效应相互对抗时，未检测到相互作用。每个系统显然都无视另一个系统的存在，配子按照独立预期产生。然而，当受影响的染色体位于同一减数分裂极时，就会发生相互作用；同时包含两种畸变染色体产物的配子的存活概率增加，而非因两种系统的联合作用而降低。
