Which statement best describes lactase persistence in humans?
Understand the Problem
The question is asking which statement most accurately describes the phenomenon of lactase persistence in humans, which is the ability to digest lactose into adulthood. This requires understanding how lactase persistence varies among different populations and is influenced by genetics and diet.
Answer
Lactase persistence is the continued activity of lactase enzyme in adulthood, allowing digestion of lactose.
