Fig 1. Haplotype frequencies for ND5 gene in studied populations and comparison with some of the populations analyzed by Albrieu Llinás and Gardenal [12].

Frequencies for H1 are indicated in red, and for H2, in green. Populations analyzed by Albrieu Llinás and Gardenal [12] are included for comparison purposes; only frequencies for H1 (light red) and H2 (light green) are indicated; all other haplotypes are in grey. Haplotype frequencies in the cities of Buenos Aires and La Plata were the same as in Albrieu Llinás and Gardenal [12]. Bordering countries: BO, Bolivia; PA, Paraguay; BR, Brazil; UR, Uruguay.
