Question

Compare the secondary sex characteristics of male and female.

Answer 1

Basis of Difference	Male	Female
Body build	After puberty, males generally develop a larger and more muscular body build.	After puberty, females generally have a smaller build and a wider pelvis.
Body hair	Males commonly develop facial hair, such as a beard and moustache, and may develop chest hair.	Females generally do not develop a beard or moustache, and chest hair is usually sparse.
Breasts	The breasts usually remain relatively undeveloped.	The breasts develop at puberty under the influence of hormones.
Voice	The voice usually becomes deeper and lower-pitched, partly because the larynx grows.	The voice usually remains higher-pitched than the adult male voice.
Shoulders and hips	The shoulders commonly become broader relative to the hips.	The pelvis commonly becomes broader relative to the shoulders.
Skin and muscle pattern	Skin often becomes coarser, and muscle development commonly increases.	Skin often remains softer, and the pattern of fat distribution commonly changes around the hips and breasts.

These are general changes associated with puberty; their extent varies among individuals. They are called secondary sex characteristics because they distinguish typical adult males and females but are not the reproductive organs themselves.
