Phylogeny of complete genomes belonging to haplogroup U7. Source of the data: nos. 1–9, present study (GenBank acc. no. EU445683-EU445691; MM=no. AndalAF_11 from Andalucia, Southern Spain (acc. no. AF382011); F1, no. 146 from Finland (acc. no. AY339547); F2, no. 147 from Finland (acc. no. AY339548); P1, no. B19 from India (acc. no. AY714013); P2, no. B81 from India (acc. no. AY714014); P3, no. C22 from India (acc. no. AY714004); A1, no. 13 from Pakistan (A Achilli, personal communication; acc. no. AY882391). The coalescence age needed to accumulate the variation within U7a2a was estimated using both control (top) and coding (bottom) region information.
