Step-by-step explanation:
Gender in the United States has been socially constructed, influenced by cultural norms and expectations. The concept of gender roles is based on norms and standards created by society, which assign certain behaviors, relationships, responsibilities, and rights differently to people of different genders. Gender categories are learned rather than inherited or inborn, making childhood an important time for gender enculturation. The specific content of gender categories is highly variable across cultures and subject to change over time.
