Verified step by step guidance

Understand the concept of secondary sexual characteristics: These are features that appear during puberty and are not directly involved in reproduction but distinguish the sexes.

Identify primary sexual characteristics: These are directly involved in reproduction, such as the production of gametes, formation of reproductive organs like the uterus, and presence of ovaries.

Recognize examples of secondary sexual characteristics: These include traits like facial hair in males, breast development in females, and changes in voice pitch.

Analyze the options given: Production of gametes, formation of the uterus, and presence of ovaries are primary sexual characteristics.

Conclude that development of facial hair in males is a secondary sexual characteristic, as it is not directly involved in reproduction but is a feature that distinguishes males during puberty.
