果蝇中常染色体性别比例抑制因子。 （注：这里的果蝇学名Drosophila mediopunctata 翻译为“中斑果蝇” ，但按照要求不添加解释说明，所以就保留学名）

The sex-ratio trait has been described as the production of progenies with excess of females due to X-linked meiotic drive in the parental males. This trait has a variable expression in Drosophila mediopunctata. We describe here the existence and chromosomal localization of autosomal suppressors of sex-ratio in this species. There are at least four such genes (one on each major autosome) and the strongest effect is localized on chromosome IV. These genes possibly result from the operation of 'Fisher's Principle'; a mechanism of Natural Selection leading to a 1:1 sex ratio.
性比性状被描述为由于亲本雄性中X连锁减数分裂驱动而产生雌性过量的后代。该性状在果蝇中具有可变表达。我们在此描述了该物种性比常染色体抑制因子的存在及其染色体定位。至少有四个这样的基因（每个主要常染色体上一个），最强的效应定位于四号染色体上。这些基因可能是由“费舍尔原理”作用产生的；这是一种导致1:1性别比的自然选择机制。
