Even between Spain and England, they find ways it's better not to mix racially when having kids.
I typed this from memory:
Bonny Bafto's off to sea
Silver buckles at his knee
He'll come back to marry me
Bonny Bobby Shafto
Bobby Shafto's fat and fair
Combing down his yellow hair
He's my love forever more
Bonny Bobby Shafto
Best to resolve traits of your own race. Everyone is different and has their own goals.
