There are many people in Thailand who look like mixed race, especially European and American Caucasians. Are they mixed race or inherited from their ancestors?

Thailand is a yellow race, a Southeast Asian race. The physical characteristics are: high forehead, flat nose, protruding mouth... very similar to some ethnic minorities in southern my country

Indians are mainly white people (most of the upper castes belong to white people), and a small number (Sudras, also known as untouchables) are yellow people. Why don't Indians look like white people? Because the hot climate and strong solar radiation in the South Asian subcontinent make Indians tan. However, the main characteristics of the white race are still retained: high nose, deep eyes, white skin and long beard. In fact, the physical characteristics of the race are closely related to the environment.
