A gender role refers to the set of expected behaviors, attitudes, and traits for males or for females. It encompasses societal norms and expectations around what is considered appropriate or desirable behavior for individuals based on their perceived gender. It is not necessarily tied to one's biological sex or a sense of being male or female, although these may influence certain aspects of gender roles. The development of secondary sex characteristics is a physical aspect of puberty that is also not directly related to gender roles.
