^aDiagonal (bold) values, within-population diversities (px); above diagonal values, net nucleotide diversity between populations (pA); below diagonal values, mean proportion of pairwise differences between populations (pxy). The 1.9-kb subset had higher than average diversity, so the values in Table 2 are adjusted accordingly (by a factor of 0.277). UK, United Kingdom; G. Bissau, Guinea Bissau; S. India, South India.
