The remains of two infants were recovered at Upward Sun River (USR), and have been dated to around 11.5 thousand years ago (ka)6.
Performance and concordance of the ForenSeq™ system for autosomal and Y chromosome short tandem repeat sequencing of reference-type specimens
In this study we investigated the performance of the ForenSeq system for aSTR and Y-STR typing by examination of 151 sample libraries developed from high quality DNAs amplified at the target 1 ng template.
Novel technologies based on sequencing long molecules and combinations of technologies, promise to stimulate the study of Y-CNVs in the immediate future.
Our study emphasizes the importance of kinship in ancient Egypt, and represents the first successful typing of both mitochondrial and Y chromosomal DNA in Egyptian mummies.
The Y chromosome as the most popular marker in genetic genealogy benefits interdisciplinary research
The Y chromosome is currently by far the most popular marker in genetic genealogy that combines genetic data and family history. This popularity is based on its haploid character and its close association with the patrilineage and paternal inherited surname.
The European paternal lineage R-DF27 has been proposed as a haplogroup of Iberian origin due to its maximum frequencies in the Iberian Peninsula.
A new study in mouse embryonic stem cells shows that telomeres and the telomeric RNA PAR-TERRA are responsible for additional pairwise interactions that guide Xic–Xic pairing.
The paper “Correlation between genetic structure and linguistic phylogeny in East Asia” by Yunzhi Huang and Hui Li provides a general landscape of correlation between population and languages in East Asia.
In this study, we collected 39 samples from China and Russia, investigated 432 samples from previous studies of haplogroup Q, and analyzed the single nucleotide polymorphism (SNP) subclades Q1a1a1-M120, Q1a2a1-L54, Q1a1b-M25, Q1a2-M346, Q1a2a1a2-L804, Q1a2b2-F1161, Q1b1a-M378, and Q1b1a1-L245. Through NETWORK and BATWING analyses, we found that the subclades of haplogroup Q continued to disperse from Central Asia and Southern Siberia during the past 10,000 years.
The presence of large and near-identical inverted repeat sequences (called palindromes) is a common feature of the constitutively haploid sex chromosomes of different species.
