A study by German scientists shows that people with blonde hair are an endangered species and will become extinct by 2202. Soon only the bottle blondes will remain, because too few people now carry the recessive gene for blonde hair. In order for a child to have blonde hair, it must receive the right gene from both sides of the family in the grandparents’ generation. They predict the last truly natural blonde will be born in Finland, which has the highest proportion of blondes.
Increased travel and immigration is bringing darker-haired people into countries where blondes once predominated. When the gene pools mix, darker hair wins out and there are fewer natural blondes born.
