Ancestral reconstruction and correlation of the frequencies of the hemoglobin S allele and the D uffy blood group alleles in human populations
Objectives : Malaria is an important selective force for human genetic adaptation due to the sustained, lethal impact it has had on populations worldwide. High frequencies of both hemoglobin S and the null allele FYB ES of the Duffy blood group have been found in areas where this disease is endemic, attributed to the protective action of the carriers of these variants against malaria infection. The objective of this work was to perform ancestral …
Identifying new lineages in the Y chromosome of Colombian Amazon indigenous populations
OBJECTIVES: The Y chromosome has highly informative markers, such as single-nucleotide polymorphisms (SNPs), that are useful for making historical inferences about the settlement of the Americas. However, the scarcity of these markers has limited their use. This study aims to identify new SNPs and increase the phylogenetic resolution of haplogroup Q for the Americas, mainly focusing on the lineages of the Amazon region. MATERIALS AND METHODS: Nex…
Genetic Variants of Duff y and Hemoglobin S Genes in an Afrodescendant Population from Colombia
Malaria is an endemic disease in a large part of Colombia, and the city of Buenaventura reports one of the highest malaria infection rates. Some genetic variants confer resistance to malaria, such as the heterozygote for hemoglobin S (HbS) and the homozygous variant FYBES/FYBES of the Dufffy gene. The aim of this work was the molecular characterization of these genes in an Afrodescendant population from the urban area of Buenaventura. A total of …

High‐resolution mitochondrial DNA analysis sheds light on human diversity, cultural interactions, and population mobility in Northwestern Amazonia
OBJECTIVES: Northwestern Amazonia (NWA) is a center of high linguistic and cultural diversity. Several language families and linguistic isolates occur in this region, as well as different subsistence patterns, with some groups being foragers and others agriculturalists. In addition, speakers of Eastern Tukanoan languages are known for practicing linguistic exogamy, a marriage system in which partners are taken from different language groups. In t…
