The one-drop rule.
His father was black, therefore he was "polluted" and considered black as well.
Barack Obama has a white mother and a black father which demonstrates the concept of one-drop rule in the US country.
Who are black people?
Black people are the individuals who are known to be African American and classified on the basis of racial classification.
In the US country, the concept of the one-drop rule is referring to the scenario where an individual belongs to the black community if one of their ancestors, that is, either mother or father belongs to the same community. Now, Obama's father belongs to the black community so he is also treated as a black individual in spite of having a white mother.
Therefore, the one-drop rule concept can be described by Obama's family.
