Define sex and differentiate between primary sex characteristics and secondary sex characteristics for both males and females
What will be an ideal response?
Sex refers to the biological and anatomical differences between females and males. At the core of these differences is the chromosomal information transmitted at the moment a child is conceived. The mother contributes an X chromosome and the father contributes either an X chromosome (which produces a female embryo) or a Y chromosome (which produces a male embryo).
At birth, male and female infants are distinguished by primary sex characteristics: the genitalia used in the reproductive process. At puberty, an increased production of hormones results in the development of secondary sex characteristics: the physical traits (other than reproductive organs) that identify an individual's sex.
For women, these include larger breasts, wider hips, and narrower shoulders; a layer of fatty tissue throughout the body; and menstruation. For men, they include development of enlarged genitals, a deeper voice, greater height, a more muscular build, and more body and facial hair.
