title: A note on the intermixture of the African black and the western European races.
abstract: Several observations seem pertinent when previous work is combined with the present investigation. The intermixture of the black and white races in the United States is an ongoing, continuous phenomenon. Different genes transfer at dissimilar rates. The concept of the time at which the Duffy blood proteins of the African black was entirely Fy should probably be extended backward to an earlier date. Calculations to derive a completely negative Fy frequency should be cushioned by the fact that intermixture of the Caucasoid and black races took place before the onset of the slave trade.
