Dominican DNA results typically show a mixed ancestry, primarily European and Sub-Saharan African, with a smaller component of Native American (Taino) ancestry. The European component is largely of Spanish and, to a lesser extent, French descent. Sub-Saharan African ancestry often includes roots from various West African nations like Senegal, Nigeria, Cameroon, Congo, Benin, Togo, Ghana, Ivory Coast, and Mali. The Taino component is significant, reflecting the indigenous population of the island of Hispaniola.
Detailed Breakdown:
European:
Dominates the ancestry, estimated at 52% in some studies, mainly from Spain and France, according to a study on medical genetics in the Dominican Republic.
Sub-Saharan African:
Makes up a substantial portion, with estimates ranging from 30-40%, according to Wikipedia.
Native American (Taino):
Represents a smaller but still significant part of the ancestry, with some studies estimating it at around 8%.
Other:
Some Dominicans may also have traces of Sephardic Jewish, Lebanese, Syrian, and Palestinian ancestry.
Regional Variations:
Cibao Region:
Some studies suggest that the Cibao region of the Dominican Republic has a higher concentration of Galician ancestry, which is closely related to Portuguese ancestry.
Migration Patterns:
Immigration from other Caribbean islands and countries has also influenced the genetic makeup of the Dominican population.
In conclusion, Dominican DNA results reflect a complex history of colonization, migration, and mixing of different populations on the island of Hispaniola.
