Category: Sex

Unlike gender identity and gender expression, sex refers to the biological and genetic differences between female-assigned and male-assigned bodies. More specifically, those assigned female at birth have two X chromosomes, and those assigned male at birth have one X and one Y chromosome. Typically, based on these chromosomes and other physical characteristics, people are grouped as either female or male.

However, contrary to popular belief, the biology of sex has a spectrum of differences that cannot be classified simply as woman and man. Some people born with a combination of sex characteristics and reproductive organs are classified on the genetic sex spectrum as intersex.
