British couple has 'black-and-white twins' twice

British couple has 'black-and-white twins' twice: "A mixed-race British couple has defied the odds — twice — by producing two sets of twins in which one sibling appears to be black and the other white. Dean Durrant's newborn daughter Miya has dark skin like him. Twin sister Leah has fair skin like her blue-eyed, red-haired mother, Alison Spooner.

Their older siblings Lauren and Hayleigh, born in 2001, also have strikingly different skin tones and eye colors.

'There's no easy way to explain it all. I'm still in shock myself,' Durrant, 33, told Sky News on Wednesday.

Both sets of twins are fraternal rather than identical, meaning they are the product of two separately fertilized eggs, so it is not unusual that they don't look alike. Miya's skin color was more influenced by her father's genes, while Leah takes after her mother.

But scientists say it's rare for a couple to have two sets of twins, end even rarer for them to have such different appearances."
