Genetic ancestry in Puerto Rican afro-descendants illustrates diverse histories of African diasporic populations.

Objectives: Genetic studies of contemporary Puerto Ricans reflect a demographic history characterized by admixture between Indigenous American, African, and European peoples. While previous studies provide genetic perspectives on the general Puerto Rican population, less is known about the island's sub-populations, specifically Afro-Puerto Ricans.

Materials And Methods: In this study, the genetic ancestry of Afro-Puerto Ricans is characterized and compared to other Caribbean populations.
