How are biracial twins different from other twins?

The genes in the sperm or egg of a biracial person usually lead to features that are a mixture of both races. However, if the genes from both the sperm and egg for one twin lead mostly to the features of one race while the genes for the other twin lead mostly to features of the other race, the twins will look like different races.
