What is the name of the explanation that suggests certain character traits are inherited from parents?

The explanation that suggests certain character traits are inherited from parents is known as genetics. Genetics is the branch of biology that deals with the heredity and variation of organisms. It focuses on how traits and characteristics are passed down from parents to offspring through genes. This process involves the transmission of genetic material, which can influence physical traits, psychological traits, and predispositions to certain behaviors or conditions.

While evolutionary theory also relates to the inheritance of traits, it primarily explains how these traits evolve over time through natural selection rather than emphasizing the direct transfer of traits from parents to children. Behaviorism and social learning theory, on the other hand, focus on environmental influences and learned behaviors rather than inherited characteristics.
