What happened to my hair?
What is the name for pattern baldness? Explain, using genetics, why more men experience male pattern baldness than women.
Can you list any other genetic traits or disorders that work the same way as pattern baldness?

Androgenetic alopecia is the name for pattern baldness.
More males then females experience this pattern baldness because of Dehydrotestosterone, or DHT, a male hormone that collects and builds up around hair follicles, eventually causing the follicle and the hair growing out of it to be killed. As DHT levels rise with aging, more and more follicles are affected by it and hair loss becomes more pronounced.
Also, There is an association of male pattern baldness with a polymorphism of the androgen receptor gene on the X chromosome. The androgen receptor gene is located on the X chromosome which is passed on from mother to male child.
If you are wondering what this " X chromose" means it is that the mother is homozygous for female children (xx) and the father is heterozygous (Yx). X= female, and Y= male. Y is the dominant trait. So if the father passes on an x, then the mother has to pass on an x therefore u have a female. If the father passes on a Y, you have a male because Y is the dominant trait.
Ok I think it will have something to do with testosterone because guys have it and girls don't and girls aren't losing their hair, or most of them aren't anyway.
hey coach. I dont know the name for the pattern of baldness. So i can't describe it by using genetics. I have to ask you, why do more man become bald than women. Because i have no idea whet the answer is to that question.
