What primarily influences an individual's chronotype?

• A. Their daily habits and routines
• B. Environmental factors like sunlight exposure
• C. The genes they inherit from both parents
• D. Their age and life experiences

Answer: (C)

An individual's chronotype is predominantly influenced by the genetic factors they inherit from both parents. Research indicates that chronotype—the natural preference for morning or evening activities—has a biological basis rooted in genetics. Specific genes related to circadian rhythms play a significant role in determining a person's sleep-wake cycles and their tendency to be a "morning person" or "night owl." While daily habits and routines, environmental factors like sunlight exposure, and age can affect sleep patterns and how one feels about their chronotype, these influences often work within the framework set by genetics. Age and life experiences may also alter a person's daily schedule and energy levels, but the foundational predisposition established by genetic inheritance is a key factor in defining one’s chronotype.
