This is amazing!

A mixed-race British mom gave birth to twins recently - one of each. No, not a boy and a girl. Two girls - one black, the other white.

The odds of such a birth are about a million to one, experts said.

Fertility experts speculate that a sperm containing all-white genes fused with an egg with all-white genes, and a sperm with all-black genes fused with an all-black gene egg to produce the fraternal twins.

的确有点奇怪.

我的猜测是父母双方都不是纯正黑人, 有白人的隐性基因.

据说肤色黑色为显性, 一个黑人要不断和白人通婚, 七代以后子孙才能漂白.但还有隐性基因.

另一种可能是基因突变.

当然也不可排除假新闻的可能.
