High Genetic Variation in Y Chromosome Patterns of the Mocoví Population

In numerically small ethnic groups, the loss of genetic variability in the Y chromosome is frequent, because this genomic compartment is often subjected to selective sweeps. Despite its small size, the Mocoví population retains a significant amount of genetic variation in relation to other native co...

Despite its small size, the Mocoví population retains a significant amount of genetic variation in relation to other native communities, but their Y chromosome diversity is not known in depth. The aim of this study was to analyze the genetic variability of the Y chromosome in a sample of Mocoví males from Santa Fe province (Argentina). We genotyped 11 short tandem repeats (STRs) and two single nucleotide polymorphisms (SNPs): M3 and M346. The diversity observed was high, and the 25 haplotypes obtained were compared to the YHRD database, with 13 of them absent of that database. A comparison with previous data reported from other Gran Chaco native groups showed significant differences between the Mocoví and other populations of different ethnic origin. This result and other studies on molecular markers of the Mocoví prove that this ethnic group retains a high genetic diversity that clearly differentiate them from other Amerindian populations. La pérdida de variabilidad genética en el cromosoma Y es frecuente en grupos étnicos reducidos numéricamente, debido a que este cromosoma suele estar sometido a barridos selectivos. A pesar de ser pequeña, la población Mocoví conserva una cantidad significativa de variación genética en relación con otras comunidades nativas, pero su diversidad a nivel del cromosoma Y no se conoce en profundidad. El objetivo de este trabajo fue analizar la variabilidad genética del cromosoma Y en una muestra de varones Mocoví de la provincia de Santa Fe (Argentina). Se tipificaron 11 microsatélites (STRs) y dos marcadores bialélicos (SNPs): M3 y M346. La diversidad observada fue elevada, y los 25 haplotipos obtenidos se compararon con la base de datos YHRD, donde 13 de ellos estuvieron ausentes. Se realizó una comparación con datos publicados de otros grupos nativos de Gran Chaco, la cual mostró diferencias significativas entre los Mocoví y algunas comunidades de distinto origen étnico. Este estudio, junto con otros realizados sobre marcadores moleculares del pueblo Mocoví, demuestran que este grupo étnico conserva una alta diversidad, que los diferencia claramente de otras comunidades amerindias.
