  • The individuals are labeled as shown in Figure 4. “No immigrant ancestry” gives the probability that the ancestry of each individual is exclusively in the geographic origin population; the following columns show the probabilities that each individual has the given amount of ancestry in the possible source population. The rows do not add to 1 because there are small probabilities associated with individuals having ancestry in the third population.
