This couple had biracial twins twice in a row, and entered the Guinness World Records

It's a very rare phenomenon. A British couple of mixed origin, Dean Durrant and Alison Spooner, had a big surprise twice in a row. In 2001, they welcomed biracial twins Hayleigh and Lauren, who had different skin and eye colours. Hayleigh was dark-skinned and dark-eyed like her father, and Lauren was light-skinned and blue-eyed like her mother. Many people find it hard to believe that they are twins; most of the time, they are simply seen as best friends.

A second miracle

In 2008, another miracle occurred. Alison Spooner once again gave birth to twin sisters, once again biracial. The father said he was very surprised by the arrival of his two daughters, named Miya and Leah.

There's no easy way to explain it all. I'm still in shock myself.

With the birth of the other two twins, the family entered the Guinness World Records.

This is the only family in the world with two sets of biracial twins. The probability of the birth of two sets of twins of different skin colors with the same parents is equal to 1 in 1,000,000.

An unusual phenomenon

The Sympa media outlet explains:

For a couple whose representatives are people of different origins, there is a chance of giving birth to a Caucasian or black child, depending on their dominant and recessive genes. Non-identical twins can be born with different skin colors when two separate eggs are fertilized by two sperm cells, which means that each of the unborn children has a different genetic heritage from that of his or her parents.
