And yet, my mother and her family are red-haired going back many generations, my children's father has red-haired uncles/aunts, and none of their descendants- children/grandchildren/gt grandchildren are red (though my son was born red, went blond and stayed that way, but with a red beard). Most of the Spencer grandchildren are blond, though Lady Sarah's son is red. None of William's kids is red. The chances of their having two red-haired children are very, very slight. None of the Markles or Raglands have claimed red hair to the best of my knowledge. Very interesting to hear from a geneticist who really knows about this stuff.
Has Meghan's father ever been asked about hair colouring in his family? It's a recessive gene, which doesn't necessarily manifest itself for generations.
In my daughter's case, none of her parents or grandparents has red hair. Nobody else in the current generation of our families does either. However, my grandmother did, so I must be carrying a recessive gene. One of my ex-husband's aunts on his father's side has red hair, which means that both have inherited a gene from a mutual ancestor. We could never work out which one because we never had any colour photos of them.
It was completely unexpected when my daughter was born with a mop of red hair. My son, who has mousy straight brown hair like I do, has already worked out that he could be carrying a recessive gene for red hair.
Hair colouring is actually quite complicated:
