How Was It Possible?
Biracial twins are a possibility, though quite rare. It happens when the parents are two different races and ethnicities. For example, Vince was Caucasian and may have had ties to the Irish. Donna, on the other hand, was half white and half Jamaican. Therefore, it makes complete sense that all of their children would be a mixed skin tone. The difference with the twins is that they had different skin colors and didn’t look the same.
The Science Behind Biracial Twins
There are two types of twins, including non-identical and identical. Maria and Lucy were non-identical because each girl was formed from a separate egg while in the womb. In a sense, two different eggs were released at the same time. Two eggs and two sperm led to Donna being pregnant with two babies with different genes. It was just happenstance that each child had a different skin color. However, there was a high probability of this happening. Find out why.
