In order to ascertain whether or not sister-chromatid exchange (SCE) differs in relation to sex, SCE rates in XX and XY cells from 10 specimens of marmoset (Callithrix jacchus) were examined. The choice of this primate is particularly suitable for three reasons: most individuals have a chimeric constitution, the X chromosome is quite large and the Y chromosome is particularly small. Therefore, the influence of possible differences in their exposure to the external environment can be eliminated. The results obtained did not reveal any significant difference between SCE rates in male and female cells in any of the examined individuals.
为了确定姐妹染色单体交换（SCE）是否因性别而异，对10只狨猴（狨属）标本的XX和XY细胞中的SCE率进行了检测。选择这种灵长类动物特别合适，原因有三点：大多数个体具有嵌合体质，X染色体相当大，Y染色体特别小。因此，可以消除它们暴露于外部环境中可能存在的差异的影响。所获得的结果并未显示在所检测的任何个体中，雄性和雌性细胞的SCE率之间存在任何显著差异。
