A couple in England, both of who have white mothers and Black fathers, had a set of fraternal twin girls. They were in for a surprise, though, when one of the twins came out looking very much like her mixed-race parents, but her sister was fair skinned, blonde, and blue-eyed. Kinda kill the whole white supremacist notion that racial mixing will completely obliterate them (that, and the fact that more than 95% of pairing are monoracial anyways). What do you guys think? Have any of you ever seen anything similar? I remember a few years ago reading about a Black women (who didn't look mixed) and her red-haired British husband having one mxed looking baby, and one blonde, extremely white looking baby. I sometimes wonder how those children chose to identify.
quote:Skin colour is believed to be determined by up to seven different genes working together.
If a woman is of mixed race, her eggs will usually contain a mixture of genes coding for both black and white skin.
Similarly, a man of mixed race will have a variety of different genes in his sperm. When these eggs and sperm come together, they will create a baby of mixed race.
But, very occasionally, the egg or sperm might contain genes coding for one skin colour. 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.
