Which of the following is NOT considered a genetic factor?

The reason that occupation is not considered a genetic factor is that it is primarily influenced by environmental, social, and personal choices rather than inherited biological characteristics. Individuals select occupations based on various factors, including education, training, interests, and economic conditions, none of which are determined by genetics.

In contrast, height, body structure, and skin color are all traits that are influenced significantly by genetic factors. These characteristics are determined by a person's genetic makeup and can be passed down from parents to offspring. Therefore, they are classified as genetic factors because they are rooted in biological inheritance rather than external circumstances or individual choices.
