People who identify as African-American may be as little as 1 percent West African or as much as 99 percent -- just one finding of a large-scale, genome-wide study of ancestry. An international research team has collected and analyzed genotype data from 365 African-Americans, 203 people from 12 West African populations and 400 Europeans from 42 countries to provide a genome-wide perspective of African and African-American ancestry.
