X-Chromosome Alu Insertions in Bahía Blanca, Argentina: Assessment of Population Information from Varied Genetic Markers and Usefulness of X-Chromosome Markers to Trace Sex-Biased Parental Contributions

Bahía Blanca is an urban city in a historically and geographically strategic location for the mixture of different populations Argentina. In present study, 10 Alu elements from X chromosome are analyzed to characterize genetic composition city’s population, compare it with other worldwide populations, explore usefulness X-chromosome markers human population genetics purposes. sample, 7 insertion frequencies polymorphic. results compared eight Africa, Europe, America. Genetic distance analysis indicates that sample closer European North African samples (average distances 0.106 0.113) than Native American (0.163) sub-Saharan (0.247). relationships shown by multidimensional scaling illustrate intermediate position groups regions (European, American, African). Admixture indicate similar proportions (0.472) parental contributions (0.479) minor contribution (0.049). These consistent past decade’s studies Argentinean reported higher previous data.
