Latin American countries are distinguished by their highly admixed populations, characterized by a significant preservation of Native American matrilineal ancestry. This contrasts with the paternal lineages, which exhibit different patterns due to pronounced sex-biased mating practices during the colonial period. Uniparental genetic markers have been instrumental in population genetics, facilitating the reconstruction of human settlement histories and serving forensic identification purposes.

In this study, uniparental markers (mtDNA and Y chromosome) were used to investigate the impact of sociocultural factors on the genetic diversity and inter-ethnolinguistic gene flow in the three major Nigerian groups: Hausa (n = 89), Yoruba (n = 135) and Igbo (n = 134). The results show a distinct history from the maternal and paternal perspectives.

CF is a multisystemic genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator gene, which mainly affects pulmonary function. P.

Its population was shaped by intercontinental admixture between autochthonous native Americans, European settlers, and African slaves. To establish forensic databases of haplotype frequencies, the evaluation of population substructure is crucial to capture the genetic diversity in admixed populations.

- The western part of the Amazon, between the Andes mountains and the beginning of the Amazon River, hasn't been studied much when it comes to the genes of local Indigenous people.
- Researchers looked at the genomes of 51 Ashaninka people from Peru and found a lot of genetic differences, leading to the discovery of at least two Ashaninka groups with unique genetic traits.
- The ancestors of the Ashaninka are believed to have migrated north from the southeast over time, interacting with many other Indigenous groups, including those who moved into the Caribbean and influenced early pottery making.
