my ex wife was very pale and blond, this was very strong traite within her family, sisters brothers ect,

one of her sisters married an indian , very black, 2 of their children were dark hair dark skin, while the boy my nephew was born very pale and very blond blue eyes, it caused a bit of argument at the time as he was in dis belief as to the bay being his, anyway proven the child was his, doctors said his skin pigment may change as he gets older, he is in his 30s now and still very blond and pale,
