Why do I have blonde hair if my parents have brown hair?

Brunettes Can Give Birth To Blondes If one parent is blonde and the other brunette, they might have a blonde child. This can only happen if the brunette parent carries the blonde allele. If he carries only brown alleles, he can only pass on brown alleles, and they’ll dominate causing his child to have brown hair.

Can two people with brown hair have a blond child?

If two brunette parents have a blond child, that means they had to have instructions for making blond hair hidden in their DNA. How could blond-making DNA be hiding in every cell of a brunette person’s body without them growing any blond hair? The answer lies in understanding ‘dominant’ and ‘recessive’ features.

Can a child be blonde if both parents have dark hair?

Absolutely, if both parents are heterozygous (BB). Black is dominant (B), while blonde is recessive (b). Therefore, if the child inherits the “b” allele from both parents, the blonde trait is now expressed, since there is no dominant gene to suppress it.

How could a child have blonde hair even though both of his parents have brown hair?

If one brown gets put in it is dominant and the hair color will be some form of brown. To have a child with blond hair the parents must both have a recessive blond gene and put in the recessive blond gene each for the child to have blond hair.

What color will my baby’s eyes be?

At birth your baby’s eyes may appear gray or blue due to a lack of pigment. Once exposed to light, the eye color will most likely start to change to blue, green, hazel, or brown over a period of six months to one year.

How can two parents with brown hair have a blonde child?

It also explains why two parents with brown hair can produce a child with blonde hair, as they both possess recessive blonde alleles in their genes, and as it is completely random which ones are passed on in the womb.

Is hair color inherited from the mother or father?

Each trait consists of two alleles, one from your Mother and one from your Father, they may be the same or they may be different. The most common gene which controls the color of our hair is a brown/blonde gene, which consists of a dominant brown allele and a recessive blonde allele.

Is it common for a baby to have blonde hair?

A of babies have blonde hair in the beginning as a baby mine was but now its black like the rest of my families. Also Typically two blonde parents will have blonde children. Blonde hair color is thought to be recessive and so both parents would have only the blonde gene to pass on to their children.

Is the brown/blonde gene dominant or recessive in humans?

A Brown/blonde gene is not the only gene pair present in humans. Another gene exists, a non-red/red pair. The non-red allele is dominant, and suppresses the production of pheomelanin, the pigment which colors the hair red, whilst the red allele is recessive. If a baby receives two red alleles, it will have red hair.
