The odds of a mixed race couple having twins of different colours are a million to one. The million-to-one black and white twins Kian and Remee turn seven. One is black and has big brown eyes. The other is a blue-eyed blonde with the palest of skin. They might share the same cheeky smile, but side by side, they could hardly look less alike. Yet remarkably, Kian and Remee are twins, born a minute apart.
Skin colour is believed to be determined by up to seven different genes working together.
If a parent is of mixed race, their eggs or sperm will contain a mixture of genetic codes for both black and white skin. However, if both the egg and sperm contain all white genes, the baby will be white. And if both contain just the versions necessary for black skin, the baby will be black.
