Dean Durrant and Alison Spooner have had two sets of black and white twins. Durrant, who is black, and Spooner, who is white, had twin girls in 2001. One of the girls was white, the other black. Seven years later, they had another set of twins. Again, one girl was white, the other black. Doctors have said that the odds of a family having a second set of black and white twins is two in a million.The Sun: Twincredibles (December 31, 2008)
Genetics
Children receive one set of genes from each parent. When separate eggs are fertilized with separate sperm, as is the case with fraternal twins, they will have different characteristics. One of the characteristics that can vary is skin color.The Sun: Twincredibles (December 31, 2008)

Quote
"“I could tell straight away that one was darker than the other. But it wasn’t as much of a shock as last time, as we had already been in this situation once...Leah and Miya are so small they haven’t been out much yet — but some people have looked at us a little bit funny when we’re with Lauren and Hayleigh due to the colour difference...Looking so different has never caused them any problems and I’m sure it won’t for Leah or Miya either. When people see Alison and I they tend to realise why our children are different." The Sun: Twincredibles (December 31, 2008)
