How do individuals learn the gender roles that society deemed appropriate? what evidence is there that gender is socially constructed?

A) simply, it starts with pink and blue (baby showers, baby clothes, gender reveals)and goes on from there( long hair, types and colors of clothes, shoes, accessories)

B) evidence such as the fact that people ask if you are a boy or a girl, assume what you like based on what you are, assume based on what color you like, assume based on what you are wearing helps prove that gender is socially constructed

I’m confused on what uu trying ask
