One-in-a-million twins born with different skin tones

These young boys are one-in-a-million because they both have different skin tones despite being twins.

Bobby and Riley George, aged three, were born just 30 minutes apart, both with light skin. But as they grew their features developed naturally in different ways.

Bobby's dark eyes turned blue and his complexion lightened at six weeks while at three months Riley's skin became darker and he grew straight brown hair.

Mum Abigail Tongue is white and their dad, landscape gardener Richard George, is mixed race.

When the boys were born in October 2011 in West Middlesex University Hospital, Isleworth, West London, they were so similar their parents could not tell them apart.

But their features quickly began to change - resulting in the differences between them today.

The boys, from Feltham, West London, have attracted attention while out in their buggy.

Strangers in the street have asked Abigail if she is babysitting Riley and whether Richard is the father of all her children.

When Bobby broke his leg in August 2013, even hospital staff did not believe the boys were twins and checked his mum's medical records - much to Abigail's frustration.

She is also worried they will be picked on when they go to school.
