Back in 2005, researchers did a similar study on, again, balding German men. They found a DNA difference on the X chromosome that was associated with going bald.
This finding fits very well with the idea that baldness can come from someone's maternal grandfather. Because each son has a 50-50 shot of getting an X from their maternal grandpa through their mom.
The X and the Y chromosome determine whether someone will be a boy or a girl. If someone has two X chromosomes, then she is almost always female. And if someone has an X and a Y chromosome, then he is almost always male.
What this means is that a daughter always gets dad's X chromosome and a son always gets dad's Y chromosome. This is why dad determines the gender of the child.
Imagine that someone has a maternal grandfather who is balding. He will give his "balding" X to his daughters. They probably won't go bald because they have an extra X chromosome from mom. The daughters will pass this "balding" X down to their sons half of the time.
I was finally able to put an end to the debate of me being 5'6" 😂😂.. Man y'all crazy. Look how much more taller I am than @black_stalwart . I'm calling @jay_swolio out next #height#usaplsc#powerlifter#bald#baldhead
