What are Scottish physical traits?

Answer 1

"white skin, blue eyes, blond hair normally but sometimes brown or red hair"

Scotland has a much higher than average percentage of people with red hair and also with the red 'gene', compared with any other country in the world. In Scotland, 13% of the population has red hair while an estimated 40% actually have the red gene. This is disproportionately high considering that, as a percentage, red heads make up less than 2% of the world's population. Red hair, is thus a very typical Scottish trait. Historically, Red headed people have only ever been recorded as a group by the Romans, when the Roman historian Tacitus described the Picts as having 'red hair and large limbs.' Modern anthropologists have now placed red hair as a unique characteristic of the Picts - Picts being the original name for the Scots.
