The definition of race is categories of human beings based on similarities in physical traits, and often confused with each other. These traits are transmitted by genes not blood; Therefore, the one-drop rule is an ineffective tool for identifying race. Instead it is discriminatory and lacks physical, anthropological and biological merits. The definition of black should be based on racial traits transferred by the genes (which are visible, and of the norm) of Sub-Sahara Africans.
