Answer:
Nature refers to heredity and nurture refers to environmental influences.
Step-by-step explanation:
By nature we mean our genetic heritage. By nuture we mean everything we learn after we are born by environmental influence. Both are responsible for forming who we are. Galton was the first to see "nature" and "nuture" as distinct entities, and to assert that both were solely responsible for personality formation.
Based on this definition, we can state that nature refers to heredity and nurture refers to environmental influences.
