Whenever you see a person with red hair, do you wonder whether they had red hair at birth? There is no exact answer to this question. Some people have red hair at birth, whereas others get it after several years. It entirely depends on the genes of that person.
As you already know, there is a strong relationship in between the genes of parents and children. From recent studies, it has been identified that parents who carry the redhead gene give birth to babies with red hair. That’s the main reason why you cannot find redheads in people of African and Asian descent as the parents don’t carry the redhead genes.
The gene that is responsible for red colored hair is recessive. Therefore, a person will need to have two copies of this gene in order to be expressed or show up. Therefore, we cannot say that redhead parents give birth to babies with red hair. Sometimes, the baby would not get red hair even if both mother and father carry red hair. Technically, one out of every four children should get red hair, if both mother and father are redheads. Sometimes a family that doesn’t have any redheads’ for centuries would give birth to a baby with red colored hair. The above mentioned fact is responsible for the same scenario as well. Whenever a baby gets a matching pair of the redhead gene, he/she will be born with red colored hair.1 | 2
