The pair owe their appearance to a one in a million combination of their parents’ genes. Mother Kylee Hodgson and father Remi Horder both have white mothers and black fathers.
The startling result is a two-tone set of delightful little girls. They first attracted international attention when they were featured in the Mail at less than a year old.
The odds of a mixed race couple having twins of different colours are a million to one. 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.
