Adult females are individuals who have reached maturity in the human species, typically defined as being 18 years or older. They possess two X chromosomes and are capable of reproduction, although not all adult females choose to have children. Their biological characteristics include the development of secondary sexual traits, such as breasts and wider hips, which are influenced by hormones like estrogen. In many societies, adult females play diverse roles, including those of mothers, professionals, and community leaders. They contribute to various fields, such as education, healthcare, and business. Adult females also advocate for gender equality and women's rights, striving for equal opportunities and representation in all aspects of life.
