‘Secret Gingers’ are people who are carriers of the recessive MC1R gene responsible for red hair, but do not have ginger hair themselves.
The gene is recessive, meaning that it can go undetected for generations, but when two MC1R-positive parents have a child, they have the potential to have a ginger baby.
In 2013, a study of more than 5,000 people by BritainsDNA found that a whopping 40% of Britons carry this gene, making the potential for red-haired babies higher than people think! And people say we’re going extinct? No way.
