Understanding how nature and nurture are distinguished in human development starts with recognizing two separate sources of influence. Nature refers to genetic inheritance—the traits and potentials passed down from parents through genes. Nurture covers environmental influences and experiences that shape how those genetic potentials are expressed, including parenting, culture, education, nutrition, and life events. This distinction helps explain why genetics set the stage, but the environment shapes how traits appear and develop.

The other descriptions mix up these roles or oversimplify the relationship. Reversing the definitions would be inaccurate, because environmental experiences do not equal genetic inheritance. Saying they are the same concept ignores that genes and environment contribute differently to development. Splitting nature to physical growth and nurture to cognitive growth is misleading, since both genetics and environment influence both physical and cognitive outcomes.
