We all learn the basics about dominant and recessive genetic traits in school. So it is common to wonder: is your hair color dominant or recessive.
Your genetics determine your hair color, specifically the gene you inherit from your parents. For example, melanin is the pigment that gives you your hair color, and the type and amount of melanin activates other proteins to determine hair color.
With the question, is blonde hair dominant or recessive? Let’s dive deep into genetics and hair color to give you the answer.
What are recessive traits?
recessive traits They are the traits that are passed down from each parent. The versions of each gene you get from your parents are called alleles.
Recessive traits can only be expressed when both recessive alleles of the gene causing the trait are present. It is impossible to inherit a recessive trait if one allele is present.
In general, a recessive trait covers the presence of the dominant traits. Also, recessive genes are less powerful than dominant traits.
What are dominant traits?
As with recessive traits, you get two versions of a gene from each of your parents.
However, unlike recessive traits, you only need one dominant trait to be present in Allah. Therefore, when there is one dominant trait and one recessive trait, the dominant trait overshadows the recessive one.
If both parents carry a dominant trait, then you will inherit the dominant trait.
If one parent carries the dominant trait and one parent carries the recessive trait, then you will also inherit the dominant trait.
In genetics, even if only one dominant trait is required, you can inherit a dominant trait from your parents.
Is blonde hair recessive or dominant?
Blond hair is a recessive gene because genetics requires both parents to be carriers of the blond gene in order to have a blond child.
However, blonde hair can skip multiple generations because the dominant gene for darker hair could have existed earlier. The overriding dominant gene can be relaxed if the same parent also carries the blond hair gene somewhere in their ancestry.
If one of the parents has dark hair and the other parent has blond hair, the child is less likely to have blond hair because the dominant gene overcomes the recessive blond gene.
and also the The baby has a 50/50 chance of blonde hair If one of the parents carries a recessive blonde trait somewhere in their genes.
While blonde hair is recessive, it is impossible to predict hair color because changes in color can happen throughout your parents’ genetics.
In addition, blond hair contains the pigment eumelanin, the cause Black or brown hair.
However, other genes you inherit from your parents reduce the amount of omelanin produced, leading to blonde hair.
Is blonde hair recessive to red?
No, blonde hair is dominant to red hair. It is dominant because blonde hair has a small amount of omelanin, which is the protein that determines hair color.
Red hair Completely different because it contains an additional pigment called pheomelanin. You get red hair from a specific mutation in the MC1R gene.
Also, the red hair pigment comes from a broken shield that cannot turn into the omelanin pigment. As a result, it remains recessive for blond hair because the parent has to carry the mutation to have a child with red hair.
Additionally, blonde hair and red hair are both recessive genes compared to brown and black hair.
Common questions
Learning about dominant and recessive traits can be overwhelming. So here are some more questions and answers to help you understand more about blonde hair.
Yes, two dark haired parents can have a blonde baby. This happens when there are blond people in the parent’s ancestry. If both parents carry the blond gene but are dark-haired, they can have a blond baby.
However, many people have hair that changes from childhood to adulthood. So, for example, if one of the parents had lighter hair as a baby, it does not pass to the child because both parents need the recessive gene.
Yes, brown hair is dominant over blonde hair because if only one parent has brown hair, their child will have brown hair.
The type of melanin that gives people hair color is omelanin. For example, people with blond hair have a very small amount of omelanin.
also, Melanocortin 1 receptor (MC1R) He is the gene responsible for determining hair color. The MC1R gene contributes to the amount of eumelanin a person has.
So is blonde hair a recessive or dominant gene?
When it comes to determining whether blonde hair is dominant or recessive, it comes down to your genetics passed down from both of your parents.
Blond hair is a recessive gene because both parents have to carry the gene for their child to inherit blond hair. If only one parent carries the gene, the child is more likely to have a different hair color.
It is important to remember that each person is unique in their own way, and their hair color only adds to the uniqueness.
