Exploring Microarray Chips

I am starting my first big adventure for the Genetic Genealogy Compendium. Four major genetic genealogy test sellers use microarray chips (Genotyping BeadChips) for products: Ancestry.com, 23andMe, Family Tree DNA, and the National Geographic Genographic Project.

The Encyclopedia of mtDNA Origins – Initial launch

This morning, I am pushing the Encyclopedia of mtDNA Origins out into the world. Each of the requirements for it is complete. What remains is doing quality assurance work and flushing out the basic background text.

The Encyclopedia of mtDNA Origins – Resources & Citizen Science

I am continuing my work on the Encyclopedia of mtDNA Origins from last time… Today, I am working on the final requirement in the project to create mtDNA pages for all named branches of our shared maternal tree. It is a list of additional resources to help the user understand and enjoy their results.

The Encyclopedia of mtDNA Origins – Sources, sources, sources

I am continuing my work on the Encyclopedia of mtDNA Origins from last time… This is a project that will create mtDNA pages for all named branches of our shared maternal tree. This time I will talk about the ninth requirement, a list of academic journal articles that mention the branch.

Evidence of early gene flow between Ashkenazi Jews and non-Jewish Europeans in mitochondrial DNA haplogroup H7

To investigate European introgression into Ashkenazi Jewry, the European-dominant haplogroup H mitochondrial DNA was examined. The results provided genetic evidence that gene flow between Jewish and non-Jewish populations occurred early in Jewish settlement in Europe with isolation of the groups thereafter.

Population structure of UK Biobank and ancient Eurasians reveals adaptation at genes influencing blood pressure

In this study, analyses of 113,851 UK Biobank samples showed that population structure in the UK is dominated by five principal components (PCs) spanning six clusters: Northern Ireland, Scotland, northern England, southern England, and two Welsh clusters.

Genetic Evidence for a Contribution of Native Americans to the Early Settlement of Rapa Nui (Easter Island)

In this review our own genetic studies of blood-derived DNA collected on Rapa Nui since 1971 are summarized. For the first time human molecular genetic data are obtained which strongly suggest that some Native Americans arrived early at Rapa Nui, probably as early as AD 1280–1495.

Outlining the Ancestry Landscape of Colombian Admixed Populations

We sought to investigate and compare patterns of genetic ancestry in Colombia by studying samples from Native and non-Native populations living in its 5 continental regions: the Andes, Caribe, Amazonia, Orinoquía, and Pacific regions. For this purpose, 46 AIM-Indels were genotyped in 761 non-related individuals from current populations.
