UA Heredity and Environment Discussion

I’m working on a psychology writing question and need the explanation and answer to help me learn.

Why is it important to determine the contribution of heredity (nature) and environment (nurture) in human development?

What would it mean if a trait develops from both genetic and environmental effects?

Do you think behaviors are learned from nature or are they nurtured? From your own real-life experience, give a specific example on a trait and how it demonstrates nature or nurture.
