According to Dr Wilson, genetically a mixed race and European couple, who are expecting twins, have about a one in 500 chance that they are of different skin colours. This chance only applies to non-identical twins, because they are conceived from two eggs fertilised by two sperm.

Genetically a mixed race and European couple, who are expecting twins, have about a one in 500 chance that the babies will have different skin colours. Fifty years ago these twin births were almost unheard of, but with the number of interracial relationships increasing, so too are the number of cases.
