Quizplus · Accepted Answer

Genetics play a role in determining one's preference for being a morning person (early bird) or a night person (night owl). This preference is related to an individual's circadian rhythm, which is the body's internal clock that regulates sleep-wake cycles. Some people may have a genetic predisposition to be morning people, while others may have a genetic predisposition to be night people.
