The influence of biological factors on human behaviour is called?

• A. Nurture
• B. Nature
• C. Sex
• D. Canalisation

Answer: (B)

The main idea here is the distinction between inherited biology and environment. The influence of biological factors on how people behave is called nature. It covers genes, hormones, brain structure, and other bodily influences that people are born with. This contrasts with nurture, which refers to the environmental factors—upbringing, culture, education, and social experiences—that shape behavior.

Nurture describes the environmental side, so it’s not the correct term for biological influence. Sex is a specific biological attribute, not the overarching concept of how biology shapes behavior. Canalisation is a genetics term about how development tends to produce certain traits despite variation, which is more about developmental stability than the general influence of biology on behavior.
