When a mother in Illinois tells strangers that her infant daughters are twins, they never believe her. That's because her daughters were born with different skin colors, making them biracial twins.
The mother is Caucasian and her boyfriend is African-American.
The mother said she was immediately surprised when she saw her daughters for the first time.
There is a 1 in 500 chance that interracial couples expecting twins will have children with different skin colors.
