Answer:
The correct answer is Heredity.
Explanation:
When we talk about the social environment, we are referring to the social and cultural conditions in which a person was raised or lives, including the people around him.
This includes culture, family and friends, but does not include heredity.
In this case, heredity is something <u>biological that is transmitted from parents to children</u>, and is not something that is part of a person's social environment.
Therefore what is not part of your social enviroment is heredity.
