Ireland at risk of losing status as reddest-headed
There is at least the potential that Ireland will be knocked off its perch as the true home of flowing red hair, as a genetics study shows more people in Scotland and Wales carry the genes that could produce future foxy generations.
Over the past year, commercial research company IrelandsDNA worked with more than 2,300 people whose four grandparents were all from England, Ireland, Scotland, or Wales, to check if they carried one of the three most common gene variants that predict red hair. If both parents carry one of the variants, there is a one-in-four chance their children will have red hair, but millions of people could have it without knowing.
