That is a statement of genetic fact from a scientific study conducted by not less than 17 Scientists published in December 22, 2009 (see link below).

The result of their study finds that majority of African Americans’ ancestry can be traced to West Africa and West-Central Africa in the following words;

Wait for them.

The sample size of 136 African-Americans matched with 102 indigenous Africans is too small to be definitive. It also says "These studies all suggest close genetic kinship among various West African, Central West African, and South West African ethnic groups." and "however, the study lacked the power to differentiate the Mandenka, Yoruba, and Bantu groups [27]. Similarly, another study examining two ethnic groups from Ghana (Akan and Gaa-Adangbe) and two from Nigeria (Yoruba, Igbo), based on 372 autosomal microsatellite markers in 493 individuals, did not differentiate these groups by genetic cluster analysis and found only modest genetic differences between them".

This SITE shows a much accurate and unbiased opinion by region and samples thousands. This SITE too.

No. African-Americans are not mostly of Yoruba ancestry. Read the paper. In the study only Mandinka, Yoruba, Bantu, Pygmy and San groups were taken to be representative of the African population.

This narrow selection is bound to produce results that will exaggerate the Yoruba element in the African-American population.

More inclusive studies will produce smaller percentages for the Yoruba.
