This has been scaled to 100%, I only did the Southern Mexican one while the rest I got them from FelipeFont who specializes in the African history of the New World

Please note that I am still putting more samples in the Southern Mexican spreadsheet so it might change a little bit but not by too much

Southern Mexicans:
51.3% West African (Almost exclusively Senegambian & Guinean)
28.8% Central & Southeastern African
1.5% Northeastern African
19.4% Broadly African

The Broadly African is high but from the spreadsheet FelipeFont made that included African groups, the only ones with a high Broadly African has been certain Central African groups and almost every South and Southeastern Africans. The Northeastern African has been popping up in Fulani people which would make sense given their history and genetics.

If we include those two components in their correct category, we get this for Southern Mexicans

52.8% West African (Including Northeastern African)
48.2% Central & Southeastern African (Including Broadly African)



Wolof
"The Wolof people are a very dark skinned, tall, proud, regal-looking people. They tend to be lazy about learning other languages, and have a domineering and contemptuous attitude toward their neighbours. and are very ethnocentric. Open sensuality is part of their lifestyle."

Fulani
"Light-skinned with curly hair, the Fulani have pointed nose, thin lips, and slender statue (Stenning 1959)"

Brazil

42.4% West African (Mostly Nigerian)
42.9% Central & Southeast African (Mostly Congolese)
0.3% Northeast African
14.4% Broadly African

Adjusting those percentages

42.7% West African (Including Northeastern African)
57.3% Central & Southeastern African (Including Broadly African)



Brazilians seem to be a mixture of Angolan, Yoruba and Mandinka

Yoruba
They were regarded as the most intelligent slave population in the Americas and even till this day they have the highest number of university graduates of Nigeria. They are the African Americans of Nigeria when it comes to talent and sports.

Mandinka
