What is the genetic advantage of balding?
Don’t lament bald heads: they may confer an evolutionary advantage by protecting you from illnesses resulting from low levels of vitamin D. Instead, think of bald heads as personal solar panels for the photosynthesis of vitamin D, the sunshine vitamin, which is vital to many aspects of health.
How exactly would a gene for baldness cause a person to become bald?
Well, many studies have shown that a crucial baldness gene is found on the X chromosome. This means that a man’s chance of being bald is linked to the genes on his X chromosome! Because of this, baldness is an example of an X-linked trait. Daughters get one X chromosome from dad and the other from mom.
Why do males go bald and females don t?
Basically, men are more prone to a condition known as androgenic alopecia. Because men are constantly producing testosterone throughout their lives, they are also constantly making DHT, and so it makes them more likely to lose their hair than women, who do not have a similar genetic disposition to hair loss.
Does being bald help grow hair?
No. That’s a myth that persists despite scientific evidence to the contrary. Shaving has no effect on new growth and doesn’t affect hair texture or density. If you’ve been shaving for a long time and then stop, you may notice some changes to new growth.
Is balding really genetic?
Hereditary-pattern baldness is not really a disease, but a natural condition caused by some combination of genetics, hormone levels and the aging process. Almost all men and women will notice hair loss or hair thinning as they age.
Do balding men have a genetic advantage?
Therefore balding men have a genetic advantage that may now be redundant. Also, baldness may confer an aerodynamic advantage when swimming, chasing prey or potential mates. A well-polished bald male head was often used by tribes of cavemen to blind predators.
What is the evolutionary reason for baldness?
One theory put foward by researchers Muscarella and Cunningham susgests baldness may have evolved in males through sexual selection as an indicator of aging and social maturity when males become less aggressive and more nurturing. I good thing for fatherhood I would say.
Does hair loss come from my mother’s genes?
Mothers carry one X chromosome from their fathers, making their grandfather’s genetics a likely indicator for what traits they will pass on to men. That being said, it would be reductive to claim that hair loss just comes from your mom’s genetics. Here is why:
Does male pattern baldness come from your mother?
There are a lot of myths and misinformation about the genetic causes of male pattern baldness (MPB). 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.
