"It just so happens that the direction for male pattern baldness is recessive. For it to happen, you must have the same pattern
on both maps. The big problem is that this gene also happens to be on the part of the map where Y is incomplete. Males only get one shot at it, while females get two. This makes it much more common in males, as all things being equal, we'd expect to see it happen half the time in males and 1/4 of the time in females. This isn't exactly true, but this is a very simplified discussion, so let's roll with it. As a quick aside, you're probably wondering why you don't see bald females very often. It does happen, of course, and many females end up with two maps that have the directions for male pattern baldness. The problem is that the symptom of the disease is triggered by the presence of testosterone. This is a chemical that men's bodies produce in abundance, but that female bodies barely produce at all. This means that you mother could actually have the directions for this to happen, but you'd never know because there's not enough testosterone in her body to make it happen"
Some researches have found that 79% of the male pattern baldness, although recessive, is heritable; and some others researches state that the gene which causes bladness, called AR (Androgen Receptors) can be found on chromosome X so this makes us wonder about so many bald biological males having both X and Y chromosome and really few bald biological females even though they have the two X chromosomes found gulity for causing baldeness.
Explanation:
The third element to be included in this equation that simplifies this discussion is: dihydrotestosterone.
Testosterone is an abundant almost exclusive male hormone responsible for bones and muscles development too, it also concerns the hair growth, the more abundant hair you get in younger ages the more bald you will get being older as abundant hair is a sign of higher testosterone levels the body is producing.
So it all depends in gene heritage probability, but the most probable is that you get the higher sensitivity of hair follicles from your mother´s family traits.
