Is Hair Color Inherited from Mother or Father? Hair color comes from both parents through the chromosomes passed onto their child. The 46 chromosomes (23 from each parent) have genes made up of DNA with instructions of what traits a child will inherit. The results can be surprising.
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Your parents provided one allele per gene at time of your conception (then these alleles paired to form your hair texture genes). It is the interaction among these alleles, not one specific gene, that determined the character of your hair.
Dr. Jennifer Chwalek: The process of hair changing from darker color to white or gray with age is mainly due to genetics. It can be inherited from either parent. The color of our hair is determined by the form of hair pigment that we have.
Men inherit the baldness gene from the X chromosome that they get from their mother. Female baldness is genetically inherited from either the mother's or father's side of the family. Baldness may be influenced by a number of other factors as well, including age, health, diet, hormones, seasonal changes and climate.
The genetic link
Genetics play a role in how much hair babies have at birth. 23andMe looks at 26 places in your DNA that influence how much hair you had at birth. There are other factors that may influence hair growth as well.
Based on identical twin studies, he and other researchers have calculated that somewhere between 79 and 81 percent of baldness is determined by genes.
Baldness can of course skip generations! If you have bald relatives on both sides of your family tree the chances are high you will be too. However, if the baldness shows up only on one side, it's highly possible the MPB gene will skip not only you but also your siblings. This is how the recessive gene works.
At what age do people typically start to lose their hair? Hair loss can start as early as your teenage years or might not occur until you're well past retirement. Generally, people begin noticing signs of hair loss in their 30s and 40s. More significant hair loss often happens when people reach their 60s and beyond.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
Who the child "gets it from" really depends on the parents' hair color and a bit of chance. For example, if one parent has dark brown hair, and the other has light brown hair, the baby will most likely get their hair color from the parent with darker hair. But it is not always so simple.
Hair thickness is an “additive" trait. This means that if you inherited two copies of the “thick hair" version of the gene (one from each parent), you'll likely have even thicker hair strands than if you only inherited the "thick hair" version from one parent.
And it is true: the hereditary factor is more dominant on the mother's side. If your dad has a full head of hair but your mom's brother is a 5 on the Norwood Scale at age 35, chances are you will follow your uncle's journey through MPB. However, the gene for MPB is actually passed down from both sides of the family.
Genetically, a person actually carries more of his/her mother's genes than his/her father's. The reason is little organelles that live within cells, the? mitochondria, which are only received from a mother. Mitochondria is the powerhouse of the cell and is inherited from the mother.
Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.

If your mom's dad is bald, then there's a high chance you'll go bald in the future. If your father is bald as well, then those chances go up even more! But even if baldness doesn't run in your mom's family, it's still possible you'll go bald.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
