How hair color is passed down is a question that has puzzled scientists for years. A new study may have finally found the answer.
According to the study, hair color is passed down through a gene called IRF4. This gene comes in different variants, which account for the different hair colors we see in the world.
The study was conducted on mice, so it’s not clear yet if the same is true for humans. But the findings could eventually help us better understand hair color inheritance in people.
It’s long been known that hair color is passed down through genes. But scientists haven’t been able to pinpoint the exact genes involved until now.
The IRF4 gene is involved in the development of melanin, the pigment that gives hair and skin their color. There are two variants of the IRF4 gene, called A and C.
People with the A variant of the IRF4 gene tend to have lighter hair, while those with the C variant tend to have darker hair.
The study found that the A variant of the IRF4 gene is passed down from parents to their children. So if one parent has the A variant, their children are likely to have it too.
The C variant, on the other hand, is passed down through the maternal line. So if a child’s mother has the C variant, they are likely to have it too.
This is the first study to identify a gene specifically involved in hair color inheritance. The findings could eventually help us better understand why some people have darker hair than others.
It’s still not clear if the same is true for humans, but the findings could eventually lead to new treatments for hair color disorders.

Can 2 brown haired parents have a blonde child?
Can brown-haired parents have a blond-haired child? This is a question that has been asked for centuries, and the answer is still not completely clear. Some experts say that it is possible for two brown-haired parents to have a blond-haired child, while others believe that this is not possible. The truth is that it is possible for two brown-haired parents to have a blond-haired child, but it is not common.
There are a few things that you should know about hair color and genetics before you try to have a blond-haired child with brown-haired parents. First of all, hair color is determined by the genes that are passed down from your parents. If both of your parents have brown hair, then there is a good chance that your child will also have brown hair. However, if one of your parents has blond hair, there is a good chance that your child will also have blond hair. This is because the blond hair gene is stronger than the brown hair gene.
Another thing to keep in mind is that hair color can also be affected by the environment. If you live in a place where the air is polluted, your child’s hair color may be darker than it would be if you lived in a place with cleaner air. This is because the pollutants can affect the color of your hair.
So, can brown-haired parents have a blond-haired child? The answer is yes, but it is not common. If you are interested in having a blond-haired child, you may want to try to move to a place with cleaner air.
How is hair color determined genetically?
How is hair color determined?
Hair color is determined by a person’s genes. The genes that determine hair color are called melanocytes. There are two types of melanocytes, the dark brown melanocytes and the light blond melanocytes. The dark brown melanocytes are the most common and they are found in the middle of the hair shaft. The light blond melanocytes are found near the hair’s surface.
Hair color is also determined by the amount of melanin in a person’s hair. Melanin is a dark brown pigment that is found in the hair shaft. The more melanin a person has, the darker their hair will be.
There are three different types of melanin, eumelanin, pheomelanin, and neuromelanin. Eumelanin is the most common type of melanin and it is found in people with dark hair. Pheomelanin is the most common type of melanin found in people with light hair. Neuromelanin is the type of melanin that is found in the brain.
What hair color is dominant?
There are six main hair colors: black, brown, blonde, red, auburn, and white. Out of these, black and brown are the most dominant, while blonde, red, and auburn are recessive. This means that if you have black or brown hair, your hair color is more dominant than if you have blonde, red, or auburn hair.
This doesn’t mean that people with blonde, red, or auburn hair can’t have children with people with black or brown hair. It just means that, statistically, there is a higher chance of a person with black or brown hair having a child with someone with blonde, red, or auburn hair than there is of a person with blonde, red, or auburn hair having a child with someone with black or brown hair.
There are a number of things that can affect a person’s hair color. Genetics is the most important factor, but the environment can also play a role. For example, exposure to the sun can cause someone’s hair to become lighter, while exposure to certain chemicals can cause someone’s hair to become darker.
What type of inheritance is hair color?
What type of inheritance is hair color?
Hair color is a trait that is determined by a gene located on the X chromosome. This gene can be either dominant or recessive. If a person has a dominant gene for hair color, they will have a hair color that is determined by that gene. If a person has a recessive gene for hair color, they will have a hair color that is determined by the gene on their other chromosome.
What is the rarest hair color?
There is no one definitive answer to this question as there are many shades and colors of hair that can be considered rare. However, some of the rarest hair colors include shades of blonde such as platinum blonde, silver blonde, and ash blonde. Other rare colors include shades of red such as auburn, ginger, and copper, and shades of brown such as chestnut, espresso, and mahogany. While any color can be considered rare, some are more rare than others.
Which parent determines hair color?
One of the most common questions that parents have is which parent determines the hair color of their child. The answer to this question is that it depends on the child’s genes.
The genes that are responsible for hair color are located on the X chromosome. This means that the hair color of a child is determined by the genes that are inherited from their mother. If the child inherits a gene for hair color from their father, then the hair color will be hidden by the gene from their mother.
There are a number of different factors that can influence the hair color of a child. The most important factor is the type of hair that the child inherits from their parents. Children who inherit curly hair from their parents will usually have darker hair than children who inherit straight hair.
The age of the parents can also play a role in the hair color of a child. Parents who are older tend to have children with lighter hair colors than parents who are younger.
The environment can also play a role in the hair color of a child. Children who live in areas that have a lot of sunlight tend to have lighter hair colors than children who live in areas that have less sunlight.
The hair color of a child is usually determined by the genes that they inherit from their mother. However, there are a number of different factors that can influence the hair color of a child.
Does hair color come from Mom or dad?
There’s no one answer to this question, as hair color is determined by a variety of factors, including genes and environment. However, in most cases, hair color is determined by the genes inherited from one’s parents.
Hair color is determined by the amount and type of melanin in the hair. Melanin is a pigment that produces different colors in hair, skin, and eyes. There are two types of melanin: eumelanin and pheomelanin. Eumelanin is responsible for darker hair colors, while pheomelanin is responsible for lighter hair colors.
Hair color is determined by the amount of melanin in the hair shaft. The more melanin a person has, the darker their hair color will be. The amount of melanin in the hair shaft can be determined by the number of melanocyte cells in the hair follicle. The number of melanocyte cells is determined by the genes inherited from one’s parents.
There are a number of genes that contribute to hair color. The most important are the melanocortin 1 receptor (MC1R) gene and the agouti signaling peptide (ASIP) gene. The MC1R gene is responsible for the amount of eumelanin in the hair, while the ASIP gene is responsible for the amount of pheomelanin in the hair.
Most cases of hair color are determined by the genes inherited from one’s parents. However, there are a number of environmental factors that can also affect hair color. Things like sun exposure, pollution, and stress can all cause hair to darken or lighten.
In the end, the answer to the question “Does hair color come from Mom or dad?” is: it depends. In most cases, hair color is determined by the genes inherited from one’s parents, but environmental factors can also play a role.
