A focused population profile of Afro-Guyanese people, their Guianese and Caribbean diaspora background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Afro-Guyanese refers to Guyanese people with substantial African-descended ancestry, shaped by slavery, plantation history, emancipation-era village formation, Caribbean regional links, and Guyana's multiethnic national history.
English is the official language, while Guyanese Creole is central to everyday speech. Afro-Guyanese identity sits alongside Indo-Guyanese, Indigenous, mixed, Portuguese, Chinese, and other Guyanese communities.
As a genetic reference, Afro-Guyanese is useful for comparison with Cameroonian Semi-Bantu, Lemande, Cameroonian Bafut, Aghem, Mbo, Manjak Gambia, Bedik, and Tikar South.
In the World Genetics modern G25 comparison, the closest non-self match for Afro-Guyanese is Cameroonian Semi-Bantu. Other nearby references include Lemande, Cameroonian Bafut, Aghem, and Mbo. This gives the Afro-Guyanese profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Afro-Guyanese ancestry is best interpreted as a Guyanese African-diaspora profile, with West/Central African-related ancestry and possible European, Indigenous American, South Asian, or other local layers depending on family history.
The heatmap should emphasize Guyana, the Guianas and southern Caribbean, and African comparison zones in Cameroon, West Africa, and Central Africa that appear near this reference.
The closest non-self match in this World Genetics comparison is Cameroonian Semi-Bantu. Other nearby references include Lemande, Cameroonian Bafut, Aghem, and Mbo.
In the current modern G25 reference set, Cameroonian Semi-Bantu is the closest listed match to the Afro-Guyanese average after removing Afro-Guyanese itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Afro-Guyanese G25 average, giving the closest-match results a geographic view.
