It's a CNN article discussing what Prince George’s skin colour would be, based on his ‘commoner’ mother’s genes. So I guess it isn't just the British media that's racist/classist:
Whatever happens, this baby might stand out genetically among royals because his mother is the first commoner to marry into the royal family since the 17th century.
“It’s very good that they’re bringing in new genes,” said Dr. Anand Saggar, a consultant in the South West Thames Regional Genetics Department at St. George’s Hospital Medical School in London. “It freshens up the gene pool.”
Catherine’s commoner genes might lead to a somewhat darker-skinned baby, Saggar said.
The royals, he explained, are pretty pale.
Catherine’s skin has a considerably more olive tone, and the baby will likely be somewhere between the two – but more like Catherine because her genes are dominant over lighter ones.
“The odds are the child will have darker skin color than the royals might be used to,” Saggar said.
