A human behavior is a combination of what he gets genetically and the environment where he/she lives in, a child may inherit the intelligence and character of their parents or ancestors. Many scientists believe that the genes have a heavy hand in personality, it is the first thing which a child gets from their parents and it just decides the basic nature of a child and an adult* when the child is grown up. Parellely there is one fact that the environment in which we live also has a huge impact on our nature, sometimes it can be so dominating that it can change an individual’s behavior completely.
