European component (n = 412)

HS0 = 76 (0.11)

HS1 = 177 (0.26)

HS2 = 185 (0.27)

European component (n = 412)

P0 = 0.45 (0.4436-0.4501)

P1 = 0.50 (0.5039-0.5104)

P2 = 0.49 (0.4926-0.4991)


Shared haplotypes between groups are also indicated; HS0, HS1 and HS2 refer to the number of shared haplotypes differing 0, 1 or 2 variants between the two main components of the urban mtDNAs (Native American and European) and the number of haplotypes (h) in the corresponding source populations. Note that these values can be > 1 because the same haplotype in the source population can count more than once for HS1 and HS2. The amount n indicates sample size. P0, P1, and P2, are the admixture components referring to sequences that match perfectly, differ by one mutational step, or two, respectively, in the database; standard deviations are in round brackets.
