Verified step by step guidance

Understand the concept of cultural relativity: Cultural relativity refers to the idea that a person's beliefs, values, and practices should be understood based on that person's own culture, rather than be judged against the criteria of another culture.

Identify the biological aspect in question: In this case, we are looking at lactose tolerance, which is the ability to digest lactose, a sugar found in milk, into adulthood.

Recognize the genetic and cultural factors: Lactose tolerance varies among populations due to genetic adaptations that have occurred in response to cultural practices, such as dairy farming and milk consumption.

Connect the concept to anatomy and physiology: The variation in lactose tolerance is an example of how cultural practices can influence physiological traits, such as the production of lactase, the enzyme that breaks down lactose.

Conclude with the example of cultural relativity: The variation in lactose tolerance among different populations illustrates cultural relativity in anatomy and physiology, as it shows how cultural practices can lead to physiological differences.
