Question

Females seldom became bald as they lack
(A) The gene for baldness
(B) Y- chromosome
(C) Male sex hormone
(D) All the above

Answer 1

Hint: The estrogen and the progesterone are the female sex hormone which maintains the female characteristics in the body. The production of the estrogen and the progesterone is more at the time of pregnancy for the growth and the development of the uterus etc. Testosterone is the male sex hormone.

Complete answer:
Although testosterone is the male sex hormone, it is also present in the female but a very little amount. This testosterone is converted into the DHT which is dihydrotestosterone with the help of the enzymes. These are called androgen. They maintain the characteristics of the male in the male body. But in the female, the testosterone does not convert into the DHT. And hence the female lacks male characteristics like bald.
The bald is the condition which is characterized by the complete or the partial absence of hairs in the skull. The male characteristics include growth of the facial hairs, deepening of the voice, broadening of the shoulders etc. The female lacks these characteristics due to the absence of the male sex hormone.

Hence the correct answer is option(C)

Note: The ovaries of the female produce both the estrogen and the testosterone. The testosterone is secreted and it maintains the body weight, correct functioning of the heart, good bone density, maintaining good memory etc
