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.
How is red hair inherited?
Red hair is a recessive genetic trait caused by a series of mutations in the melanocortin 1 receptor (MC1R), a gene located on chromosome 16. As a recessive trait it must be inherited from both parents to cause the hair to become red.
Can a baby have red hair if the parents don t?
In order to be a redhead, a baby needs two copies of the red hair gene (a mutation of the MC1R gene) because it is recessive. This means if neither parent is ginger, they both need to carry the gene and pass it on — and even then they will have just a 25% chance of the child turning out to be a redhead.
Is red hair the rarest hair color?

Is red hair inherited from mother or father?
Both parents can display recessive gene characteristics, and they can pass those to their children, too. For example, if both parents have red hair, a child receives mostly the genetic information for red hair, so the chances they will have red hair is almost 100 percent.
Do Babies red hair change?
Hair Color Changes Throughout Life

Will 2 redheads have a redheaded baby?
