A project is being launched which aims to find out how many people in Scotland carry the red hair gene.
Researchers from the ScotlandsDNA project also hope to discover why Scotland appears to have the most red-headed people in the world.
Only about 1-2% of the world's population has red hair, but in Scotland the figure is much higher at around 13% or about 650,000 people.
The information will be used to make a "ginger" map of the British Isles.
