The karyotype and paternal social class were determined for 10,348 consecutively born males. No significant difference in paternal social class was associated with the occurrence of the XYY or the XXY karyotype. This argues against the suggestion that socioeconomic factors significantly affect the frequency of the nondisjunctional events leading to these chromosome abnormalities.
对10348名连续出生的男性进行了核型和父亲社会阶层的测定。父亲社会阶层与XYY或XXY核型的发生之间没有显著差异。这与社会经济因素会显著影响导致这些染色体异常的不分离事件频率的观点相悖。
