Question

Accessory sex character is
A. Beard
B. Breast
C. Moustaches
D. All the above

Answer 1

Hint: In humans sex organs or primary sexual characteristics are those characteristics a person is born with. These primary or accessory sexual characteristics are different from secondary sex characteristics as they develop later in life, usually during puberty.

Complete answer: Sexual characteristics are behavioural or physical traits of an organism which are indicative of its biological sex. Sexual characteristic includes sex organs used for reproduction. Secondary sex characteristics help in distinguishing between the sexes of a species, but they are not directly part of the reproductive system. Accessory sex characters are changes that occur in females and males. These changes occur due to the secretion of a high level of male and female hormones like:
a) Testosterone in male
b) Estrogen in females.
Some examples of secondary sexual characteristics in males are Adam's Apple, moustache, beards, etc. whereas in females are the growth and broadening of the pelvis, breasts etc., All these changes occur during puberty. The development of both primary and secondary characteristics is controlled by sex hormones produced by the body after the initial fetal stage. Development is determined by the presence or absence of the Y-chromosome and/or the SRY gene.
So, the correct answer is option D.

Note: Secondary sex characteristics are features that appear during the puberty period in humans and at sexual maturity in other animals. Some of the male secondary sexual organs include prostate gland, seminal vesicles, bulbourethral glands, etc.
