Mitochondrial diversity in Amerindian Kichwa and Mestizo populations from Ecuador

Abstract

This study presents mitochondrial DNA (mtDNA) data from 107 unrelated individuals from two of the major ethnic groups in Ecuador: Amerindian Kichwas (n = 65) and Mestizos (n = 42). We characterized the diversity of the matrilineal lineages of these Ecuadorian groups by analyzing the entire mtDNA control region. Different patterns of diversity were observed in the two groups as result of the unique historical and demographic events which have occurred in each population. Higher genetic diversity values were obtained for the Mestizo group than for the Amerindian group. Interestingly, only Native American lineages were detected in the two population samples, but with differences in the haplogroup distribution: Kichwa (A, 49%; B, 3%; C, 8%; and D, 40%) and Mestizo (A, 33%; B, 33%; C, 10%; and D, 24%). Analysis of the complete mtDNA control region proved to be useful to increase the discrimination power between individuals who showed common haplotypes in HVSI and HVSII segments; and added valuable information to the phylogenetic interpretation of mtDNA haplotypes.

“…). In addition, for haplotype comparisons, we included published data for Quechua‐speaking people from the Pastaza River, labelled as Kichwa_PTZ (n = 65 for mtDNA, n = 28 for Y‐chromosome) from Ecuador (Baeta et al., ; Roewer et al., ).…”

Exploring the mitochondrial DNA variability of the Amazonian Yanomami

“…The comparative sample included: Shamatari sample from Williams et al (2002); a Yanomami sample from the Roraima region in Brazil (herewith named Roraima Yanomami) (Merriwether et al, 2000); and a Yanomami sample from Venezuela (herewith named Venezuelan Yanomami) (Merriwether et al, 2000) (Supporting Information Table S1 and Fig. Data from other populations living in different Amazonian regions were also used for comparison (Baeta et al, 2012;Cardoso et al, 2012;Marrero et al, 2007;Tamm et al, 2007;Vona et al, 2005;Ward et al, 1996) (Supporting Information Table S1 and Fig. Data from other populations living in different Amazonian regions were also used for comparison (Baeta et al, 2012;Cardoso et al, 2012;Marrero et al, 2007;Tamm et al, 2007;Vona et al, 2005;Ward et al, 1996) (Supporting Information Table S1 and Fig.…”
