Are ethnicity and culture related?

Ethnicity and Culture are distinct and independent. Ethnicity refers to the national background of an individual. 

Conversely, culture encompasses the customs, language, and religion that characterize a specific group's way of life.

Culture and Ethnicity are independent. Ethnicity has to do with the division of groups of individuals based on their ancestry and the special characteristics of the society they were born into. On the other hand, Culture explains the characteristics of a specific society.
