Heredity Determines Personality

"Heredity determines personality." (a) Build an argument to support this statement. (b) Build an argument against this statement.
Personality is defined as the sum total of beliefs, behaviors, attitudes and values that distinguishes an individual. Each of us has unique personalities which distinguish us from the others. Even twins who look alike and are brought up in the same environment, differ in personalities. A number of factors determine a person’s personality. These include environment and genetics. Our personality is the product of the interaction of these two factors. It is not exclusively molded by the environment or genetics but a combination of both.
Support

As a human being, we have certain characteristics which mainly comes from our genetic inheritance. Therefore one’s personality is dependent on heredity. For example, we use words like father like son; she has her mother’s temperament.

In addition, a people grow up in their family would pick up their parents habits and also try to behave like them. As a result, heredity does limit the individual’s personality trait.
Moreover, we all know that every person put up with similar gene with their parents which are to be found in their chromosome. Therefore, Heredity determines personality.

Against

People play different role at different situation and environment. A person learns it from their culture and from their social groups. Different culture also has a different way of handle activities and situation. Therefore we try to take in the good cultural values, norms and so many things to define who we are.
Our religion determines our personality too. Such as, people who come from Christian religion their personality and believe, obviously differ from another religion and vice versa.
Experience also plays an important role in shaping our personality to be more mature. For example, when a female colleague expressed her anger to a male colleague openly in the office. Everyone will have a negative perception about her as well as embarrassing herself. Therefore, she would have learned from this experience by not repeating it and use a different approach to the situation.

From the above explanations and examples given, it seems to me that not only heredity determines personality but also the environment and situation.
