Answer 1

Answer:

Gender identity is the personal sense of one's own gender.[1] Gender identity can correlate with a person's assigned sex at birth or can differ from it.[2] Gender expression typically reflects a person's gender identity, but this is not always the case.[3][4] While a person may express behaviors, attitudes, and appearances consistent with a particular gender role, such expression may not necessarily reflect their gender identity. The term gender identity was originally coined by Robert J. Stoller in 1964.[5]

All societies have a set of gender categories that can serve as the basis of a person's self-identity in relation to other members of society.[6] In most societies, there is a basic division between gender attributes assigned to males and females,[7] a gender binary to which most people adhere and which includes expectations of masculinity and femininity in all aspects of sex and gender: biological sex, gender identity, and gender expression.[8] Some people do not identify with some, or all, of the aspects of gender assigned to their biological sex;[9] some of those people are transgender, non-binary or genderqueer. Some societies have third gender categories.

Gender identity is usually formed by age three.[10][11] After age three, it is extremely difficult to change[11] and attempts to reassign it can result in gender dysphoria.[12] Both biological and social factors have been suggested to influence its formation.

Answer 2

Answer:

Most children typically develop the ability to recognize and label stereotypical gender groups, such as girl, woman and feminine, and boy, man and masculine, between ages 18 and 24 months. Most also categorize their own gender by age 3 years.

Who is responsible for baby gender?

Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY)
