Greater prevalence of Y chromosome Q1a3a haplogroup in Y-microdeleted Chilean men: a case–control study
(SPRINGER/PLENUM PUBLISHERS, 2013-02-08)
To determine the prevalence of South Amerindian Y chromosome in Chilean patients with spermatogenic failure and their association with classical and/or AZFc-partial Y chromosome deletions.
We studied 400 men, 218 with ...
Genetic structure and gene flow in Gran Chaco populations of Argentina: Evidence from Y-chromosome markers
(Wayne State University Press, 2004-12)
The Gran Chaco region of central South America has been settled by humans for only the last 4,000-5,000 years. To investigate population structure and variation in this region's indigenous population, we scored males from ...
Chromosomal features of nucleolar dominance in hybrids between the Neotropical fish Leporinus macrocephalus and Leporinus elongatus (Characiformes, Anostomidae)
(Springer, 2009-11-01)
In the present study, the chromosomal mechanisms of nucleolar dominance were analyzed in the hybrid lineage Piaupara, which resulted from crossing the Leporinus macrocephalus female (Piau double dagger u) and L. elongatus ...
On the Origin of Cattle: How Aurochs Became Cattle and Colonized the World
(Wiley-Blackwell, 2010-07-01)
Since their domestication in the Neolithic, cattle have belonged to our cultural heritage. The reconstruction of their history is an active field of research 1 that contributes to our understanding of human history. ...
História genética das populações peruanas
(Universidade Federal de Minas GeraisUFMG, 2013-02-28)
The current Peruvian populations were mostly derived from two major migratory events, one ancient or pre-Columbian and another more recent or post-Columbian. In this study, we attempt to reconstruct the impact of these ...
Integrative analysis of chromosome banding, telomere localization and molecular genetics in the highly variable Ctenomys of the Corrientes group (Rodentia; Ctenomyidae)
(Springer, 2018-10)
The genus Ctenomys comprises about 70 species with great chromosome diversity. The Corrientes group is one of the most chromosomally variable lineages in the genus, where the diploid number (2n) varies from 41 to 70. In ...

Human Y-chromosome SNP characterization by multiplex amplified product-length polymorphism analysis
(Wiley VCH Verlag, 2014-05)
We designed an allele-specific amplification protocol to optimize Y-chromosome SNP typing, which is an unavoidable step for defining the phylogenetic status of paternal lineages. It allows the simultaneous highly specific ...
