True
Determining the cause of human variation can be difficult because there are several factors that can influence an individual's traits and characteristics.
These factors include genetics (i.e. the genes a person inherits from their parents), environment (i.e. the social and physical environment in which a person is raised), and culture (i.e. shared beliefs, values, habits) included. by a group of people).
All of these factors can contribute to the variability seen among people, and it can be difficult to elucidate their relative contributions.
Genetics play a role in determining an individual's traits and characteristics, as genes provide instructions for the development and function of the body's cells, tissues, and organs. For example, genetics can influence a person's physical characteristics such as height, eye color, facial features, and risk of certain diseases and conditions.
