Solution

size of body

Explanation:

Inherited traits are passed from parents to offspring through genes. The colour of eyes, colour of skin, and nature of hair are inherited traits. However, the size of the body is greatly influenced by environmental factors such as nutrition, exercise, and health, so it is not considered a purely inherited trait.
