What races can have blue eyes?

Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago. That individual is a common ancestor of all blue-eyed people today.

Will my child have red hair?

If one parent is redheaded and the other isn’t, the chances their child will have red hair is about 50 percent, though the shade of red may vary greatly. Lastly, if both parents are carriers of the gene variant but don’t have red hair, the child has about a 1 in 4 chance of having truly red hair.

For all those brunettes wishing they were naturally blond, a small genetic change could have made all the difference. Scientists have found that replacing one of DNA’s four letters at a key spot in the genome shifts a particular gene’s activity and leads to fairer hair.
