Abstract
The sex-ratio trait--production of progenies with excess of females due to X-linked meiotic drive in parental males--has a variable expression in Drosophila mediopunctata. We tested the effect of male age and found that aging increases the expression of sex-ratio, a fact relevant for the interpretation of field data and for experimental design.
摘要
性比性状——由于亲本雄性中X连锁减数分裂驱动而产生雌性后代过多的现象——在果蝇中具有可变表达。我们测试了雄性年龄的影响，发现衰老会增加性比的表达，这一事实对于野外数据的解释和实验设计具有重要意义。
