What is the difference between gender and sex? 

Sex refers to the biological aspects of a person, typically categorized as male or female based on physical characteristics such as body parts, hormones, and reproductive systems. Gender, on the other hand, is about personal identity—how individuals perceive themselves and how they want to be recognized by others. It involves how people feel inside and how they relate to societal expectations. Gender is not confined to male or female, and people can identify as non-binary, gender fluid, or other identities outside the traditional binary.

Describe the difference between cisgender and transgender person. 

A cisgender person is someone whose gender identity matches the sex they were assigned at birth. For example, someone assigned female at birth who identifies as a woman is cisgender. A transgender person, however, is someone whose gender identity does not align with the sex they were assigned at birth. A transgender person may identify as the opposite gender or may identify as non-binary or gender fluid, and they might undergo a process of transition to align their appearance, pronouns, and name with their gender identity.

What is gender expression? 

Gender expression refers to the way individuals present their gender through their actions, appearance, and behavior. This includes the clothes they wear, how they style their hair, the pronouns they use (such as he, she, or they), and the way they interact with others. It is a personal and unique representation of how a person feels about their gender, and it can vary widely between individuals. Gender expression is fluid and can change over time, reflecting how a person feels about their gender identity at any given moment.
