2. To which class of the above Male pattern baldness belongs to? An explanation will be a great help. I am confused with Pattern baldness because 2 different books have classified it differently.

Think of things that only women can do, or things that only men can do, i.e. women producing milk. Sex-influenced traits are expressed in both males and females but are expressed differently in each sex, and they are autosomal meaning not found on the x and y chromosomes. One example would be eye color.

I believe the gene for male pattern baldness is found in the x chromosome. Title: Re: Sex limited & Sex influenced traits. Post by: Avradeep on Sep 6, 2015 Thanks a lot padre.
But pattern baldness is more common in men. So should not it be located on Y chromosome? Title: Re: Sex limited & Sex influenced traits. Post by: bio_man on Sep 6, 2015 Thanks a lot padre. But pattern baldness is more common in men. So should not it be located on Y chromosome? Both genders experience hair loss. Male pattern baldness is caused by the conversion of testosterone into dihydrotestosterone. This conversion occurs at the prostate gland and at the hair follicle. At the hair follicle, it reduces blood flow to the area. |
