Verified step by step guidance

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

Identify examples of secondary sex characteristics in males: These include the development of facial hair, deepening of the voice, and increased muscle mass.

Consider the options provided: Development of facial hair in males, Presence of ovaries, Formation of the zygote, Production of gametes.

Analyze each option: Presence of ovaries and production of gametes are primary sex characteristics as they are directly involved in reproduction. Formation of the zygote is a process, not a characteristic.

Conclude that the development of facial hair in males is a secondary sex characteristic, as it is a feature that appears during puberty and is not directly involved in the reproductive process.
