该研究主要基于冷战时期的数据,但是有关未来的核灾难将对出生婴儿性别产生影响的研究发现和现在却有很大关联。
And in the wake of Japan's Fukushima Daiichi nuclear power plant accident experts are predicting another baby boy boom could be imminent, especially on the U.S. West Coast.
专家预测,在日本福岛第一核电站事故之后,将出现又一轮“男婴潮”,尤其是在美国西海岸。
Previous radiation experiments on animals may give a clue for the increase in male births. Tests showed that radiation caused damage to the X chromosomein sperm, Dr Scherb said.
舍布博士称,先前在动物身上做的核辐射实验对于男婴出生率的增高可能会提供一些线索。实验表明核辐射会对精子的X染色体造成损害。
A human sperm cell contains either an X or Y chromosome, while an egg only has a X chromosome. An XY combination will become a boy, while an XX combination will be a girl.
人体精子细胞包含X或Y染色体,而卵子只包含X染色体。XY染色体的结合会生出男孩,而XX染色体的结合会生出女孩。
