In spite of these differences, the construction of race in Latin America can be contrasted with concepts of race and ethnicity in the United States. (wikipedia.org)
Another difference between race and ethnicity is that race is usually conceptualized as a system of categorization where membership is limited to one category and is externally ascribed by other who are not members of that category without regards to the individuals own feeling of membership. (wikipedia.org)
Unlike the United States where ancestry is used to define race, Latin American scholars came to agree by the 1970s that race in Latin America could not be understood as the "genetic composition of individuals" but instead "based upon a combination of cultural, social, and somatic considerations.

There is no single system of races or ethnicities that covers all modern Latin America, and usage of labels may vary substantially. (wikipedia.org)

Racial categories in Latin America are often linked to both continental ancestry or mixture as inferred from phenotypical traits, but also to socio-economic status. (wikipedia.org)
Racial and ethnic discrimination is common in Latin America where socio-economic status generally correlates with perceived whiteness, while indigenous status and perceived African ancestry is generally correlated with poverty, and lack of opportunity and social status. (wikipedia.org)

An Ancestry Test in India is done for different purposes, like finding out the paternal lineage and maternal lineage. (dnaforensics.in)
A Maternal Lineage Indian Ancestry DNA Test is based on the fact that mitochondrial DNA (mtDNA) is passed down from the mother to the child relatively unchanged through several generations. (dnaforensics.in)
