Final answer:
Ethnicity refers to inherent traits like genetic backgrounds and physical features, as well as aspects such as birthplace, language, and religion, which help define a group's collective national identity.
Step-by-step explanation:
The shared language, religion, and national origin of a particular group of people refer to their ethnicity. This term encompasses the inherent traits people are born with, such as genetic backgrounds and physical features, as well as aspects tied to the birthplace. In contrast, culture comprises the learned behaviors, customs, traditions, and languages that are acquired after birth and can change based on individual choice. The concept of a nation often correlates closely with ethnicity, as nations may be formed around a shared language, religion, origin, or a combination thereof, establishing a collective national identity. Ethnicity is deeply rooted in the way groups define themselves and is distinct from shared cultural practices or traditions.
