PARIS (AFP) – Doctors in France on Monday announced the country's first
birth of a "saviour sibling," selected at the embryonic stage to be a close
genetic match to save a brother or sister suffering from a fatal inherited
disorder.
The baby was born at the Antoine Beclere Hospital in Clamart, in the suburbs
of Paris, said doctors Rene Frydman and Arnold Munnich.

前两年有一个网上广泛流传的说法，据说决定智商的八对基因全部都是位于X 染色体上
面，然后男生是XY，X 是来自母亲，Y 是来自父亲。
所以男生的智商全部都是来自母亲的遗传。

这个“据说”，也就是“决定智商的八对基因全部都是位于X 染色体上面”，实际上查

博主甚至怀疑，这个说法是某个聪明但不貌美的女子编造的谎言。
