Donna Was a Mixed Lineage
It all comes down to Lucy and Maria’s mother, Donna. Since she was of a mixed lineage, there was a higher chance that one twin would come out white/light, and the other would be darker. Donna carried a gene for black and white skin. Therefore, she could pass on the white gene to either or both children. The opposite applied: Donna could also give the black gene to one or both of her kids.

How Rare Are Biracial Twins

Though rare right now, twin experts predict that there could be an increase because mixed-race couples are also more common. However, the stigma associated with skin color is paramount here. Most people don’t believe that the mother has a child with the same skin tone as her other children AND one that looks completely different.
