Scientists have discovered genes linked to red hair, helping to solve a mystery of how redheads inherit their flaming locks. Scientists have discovered eight genes linked to red hair. The study what genetics determine hair color which also sheds light on blondes and brunettes — is the largest genetic study of hair colour to date.

It had been thought what does making mud mean red hair is controlled by a single gene, called MC1R. The new research sheds light on other genes that are involved. Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair — one from their mum and what genetics determine hair color from their dad. Although almost everyone with red hair has two copies of what genetics determine hair color red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.

Scientists knew there must whaf other genes involved but these have mostly remained a hait until now. Comparing redheads to people with brown or black hair, they identified eight previously unknown genetic differences that are associated with red hair. The team also fetermine at the functions of the genes they identified and found that some of them work by controlling when MC1R is switched on or off.

In addition to the redhead genes, the researchers uncovered differences in almost genes associated with blondes and brunettes. Scientists say there is a gradient of colour from black, through dark brown to light brown and blonde, which colo caused what is a causal relationship increasing number of genetic differences in these genes.

The researchers were surprised to find that many of these genetic differences were associated oclor hair texture rather than pigmentation. Others are involved in determining how the hair grows — whether curly or straight, for example. We were able to use the power of UK Biobank, a huge and unique genetic study of half a million people in Britain, which allowed us to find these effects. We are very pleased that this work has unravelled most of the genetic variation contributing to differences in hair colour among people.

Once again collaborative research determmine helping to provide answers to some of life's important questions.
