The two notions are related to biological and sociological factors. Race is about the physical characteristics, like skin or hair color, while ethnicity refers to culture including nationality, ancestry or language. It means a population group where the members identify one other on the basis of their history, nationality or shared cultural traditions. Race is about to divide people into populations based on physical features. Ethnic groups tend to distinguish themselves differently from one period to another, while races are distinguished by skin color or face, for example. Ethnicity is about shared cultural traits, like historical or linguistic one. Race assumes common biological or genetic traits, weather realistic or asserted. In short, ethnicity is about cultural values, while race is about physical characteristics.
