Group-specific component (GC) in Curiau and Pacoval, two African-derived Brazilian populations

Article Abstract:

The group-specific component (GC) has been analyzed in two African-derived Quilombo populations from Curiau and Pacoval in the Brazilian Amazon. With high frequencies of GC*1F and lower frequencies of GC*1S, these populations are similar to each other and to other African-derived Brazilian populations, as well as to African populations, but unlike Europeans and South American Indians.
