Does paternal grandfather determine baldness?

Basically, if your maternal grandfather went bald, there’s a good chance that you have some of the X chromosome genes for baldness, and some chance you have the autosomal genes for it too. (You can find out with a bit more certainty, for two of the genes on chromosomes X and 20, by taking a genetic test.)

Does bald hair skip a generation?

There is no scientific basis for the idea that baldness skip generations, regardless of any old wives tales you may have heard from the grapevine. However, there are many reasons why some people in families which carry the genetic trait for baldness do not go bald.

Which parent do you inherit hair from?

One of the most enduring is that you inherit it from your mother. While there is some truth to this, it is not the whole story. If you’re a man, you got your X chromosome— which either has or does not have the variation of this gene that promotes baldness—from your mother.

What age does genetic hair loss start?

It usually begins about the age of 30, becomes noticeable about the age of 40, and more noticeable after menopause. By the age of 50 at least a quarter of women experience some degree of hair thinning.

Is thick hair genetic?

Genetics strongly influence human hair thickness. 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.

Is baldness hereditary from mother or father?

Baldness happens because of the genes people inherit from both their mom and dad. Some studies show that 80\% of balding is genetic. A key gene can come from a maternal grandpa. But this gene doesn’t explain all baldness. People are just as likely to be bald if their dad or their maternal grandfather is bald.

Do daughters pass on baldness to their sons?

The daughters will pass this “balding” X down to their sons half of the time. Researchers found a piece of the X chromosome that tended to be shared in balding men. They were able to narrow down the region on the X chromsome to a single gene — the androgen receptor (AR) gene.

Can a son be a carrier of the baldness gene?

Any sons who inherit the gene are very likely to be bald. Any daughters who inherit the gene will be carriers, like their mother. Now, let’s say you did receive the X chromosome with the baldness genes, and you eventually go bald. What will your children’s hair be like?

Could 20p11 chromosome play a role in balding?

Two new studies have fingered a small region on chromosome 20 called 20p11 as being associated with balding. This sort of thing could explain people who are bald even though their mom’s dad still has a full head of hair.
