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.
When we casually observe via our eyes, we may feel that we have inherited most of our hair features from either our mom or dad. However, the reality is that we inherit equal volume of genetic information from both mom and dad.
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.
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.
Inherited traits include things such as hair color, eye color, muscle structure, bone structure, and even features like the shape of a nose. Inheritable traits are traits that get passed down from generation to the next generation.

Your baby's DNA comes in packages of alleles. These are either “dominant” or “recessive.” For hair color, the dominant alleles produce darker shades, whereas the recessive ones create lighter tones (4).
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.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
From 9 months through age 2 1/2, the color trend lightened. After age 3, hair color became progressively darker until age 5. This just means that your baby's hair may change shades a few times after birth before settling on a more permanent color.
DNA. Everyone knows that DNA is what determines your baby's appearance. But DNA is a very complex subject. Everything from hair color, eye color, height, and weight to the placement of dimples or freckles can be dictated by you or your partner's (or both!)
Curly hair is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you a curly-haired gene and the other parent gives you a straight-haired gene, you'll be born with curly hair.
Physical features. Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your 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.
The egg and sperm together give the baby the full set of chromosomes. So, half the baby's DNA comes from the mother and half comes from the father.
A newborn usually looks like the father, they say. Although it is certainly not an established fact that your little one soon will look more like daddy, there are several studies known that have shown this to be true.
Male fetal progenitor cells persist in maternal blood for as long as 27 years postpartum.
In order to be a redhead, a baby needs two copies of the red hair gene (a mutation of the MC1R gene) because it is recessive. This means if neither parent is ginger, they both need to carry the gene and pass it on — and even then they will have just a 25% chance of the child turning out to be a redhead.
So what does that all mean for your chances of having a red-headed child? Since you need two pieces of “red hair” DNA to have red hair, your child will only have red hair if they receive “red hair” DNA from both parents. Even if you don't have red hair, you can still pass on a red hair allele to your child!
Red hair is a recessive trait, which means that only those who get two “redhead” versions of the gene, one from the mother and one from the father, will have red hair.
Black hair are dominant over brown hair.
The story of human migration and evolution is written in hair DNA. In sub-Saharan Africa, genes favour tight, curly hair. But in east Asia, mutations have led to straighter, thicker hair. In Europe, other mutations brought wavy and straw-coloured hair.
Curly hair is not certain to a race or ethnicity, it appears all over the world in many forms. White, brown, black and everything inbetween! There is also a scale on which curly hair is classified (2a-4c).
