They are often the butt of cruel jibes and perhaps blame it on their parents’ genes.
But now research suggests that redheads can in fact put their colouring down to the weather.
Experts believe that Scotland’s gloomy climate has seen a deliberate genetic adaptation to help exploit rare sunny days and boost Vitamin D production.
Alastair Moffat, managing director of the ScotlandsDNA project, said the country’s dull weather was responsible for a larger number of flame-haired men and women being born.
Only about 1-2 per cent of the world’s population has red hair but in Scotland the figure is much higher, with about 13 per cent, or 650,000 people, with flaming locks.
