Final answer:
The term for expressions of sex and gender diverging from traditional norms is gender nonconformity. Related to this is genderqueer, reflecting identities beyond the binary model. Societies may have multiple gender systems accommodating such diversity.
Step-by-step explanation:
Understanding Gender Nonconformity and Variant Gender
The term that refers to expressions of sex and gender that deviate from traditional male and female norms is gender nonconformity. Gender nonconformity describes when an individual's gender expression or identity does not align with societal expectations of masculinity or femininity. Another related terminology is genderqueer, which denotes a person who does not subscribe to conventional gender distinctions but identifies outside of the binary male/female framework.
More broadly, some societies recognize multiple gender systems that include additional categories beyond male and female to include people with variant gender identities. Within these systems, an individual might adopt a category that diverges from their assigned sex at birth, transitioning to what culturally may be considered a variant gender. These sociocultural understandings of gender accommodate a spectrum of diversity in sex/gender identity and expression that may be celebrated, regarded indifferently, or discriminated against in different cultures. Intersex individuals, for example, may demonstrate biological characteristics that do not fit neatly into the male or female categories, which also highlights the complexity surrounding the concepts of sex and gender.
