This can happen as a result of nondisjunction of sex chromosomes during meiosis, and it happens more frequently in sperm cells - but egg cells can also be affected.
这可能是由于细胞在减数分裂期间性染色体未分离而造成的，而且这一情况在精子细胞中发生得更频繁，不过在卵细胞中也可能出现。

Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
