Is length of hair genetic?
The regulation of human hair growth is one of the most mysterious of biologic events. Genetic factors are responsible for the density, length, color and texture of hair.
Which parent determines the hair of the child?
Human DNA has millions of on and off switches along networks that control how genes function. Genes responsible for hair color come from both parents. Although the genes passed down from a child’s parents determine hair color, variations can result in a child having a different hair color than both parents.
Is hair length inherited from parents?
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.

Do genetics play a part in hair growth?
Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
What genes do daughters get from fathers?
As we’ve learned, dads contribute one Y or one X chromosome to their offspring. Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother.
Can two blonde parents have a kid with brown hair?
You got one from each of your parents. What happens if you got a ‘brown’ allele from your mother, and a ‘blond’ one from your father? 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.
