• PCA Based Ethnic Origins – Part 7, Autosomal SNP Genetics 101

  Sometimes, I read something, and it is so very wrong, I feel morally responsible for the person who wrote it not knowing better. Not that I have caused it mind you, but that I am falling short as a genealogy and genetic genealogy educator. This was the case when I read some text on one of the testing companies websites a few weeks ago.

   

• PCA Based Ethnic Origins – Part 6, Genealogical markers

  It is day six, and we are back to genealogy. The only thing that is going to change PCA ethnic origins into a meaningful product for genealogists and even for personal ancestry enthusiasts is to use markers that date to the genealogical and historic time frames.

• Ireland – A Place

  Ireland is also known as the Republic of Ireland. It is an island nation in Northwestern Europe. It lies to the west of Great Britain. The Republic of Ireland occupies five-sixths of the island of Ireland in the North Atlantic Ocean.

  
   

• Y-DNA Testing for Genetic Genealogy

  Y-chromosome DNA, Y-DNA, testing for genetic genealogy is both the second most common type of DNA testing for genealogy and the second type of DNA test to be used in academics to study population histories.

• Skeletal Anomalies in The Neandertal Family of El Sidrón (Spain) Support A Role of Inbreeding in Neandertal Extinction

  Neandertals disappeared from the fossil record around 40,000 bp, after a demographic history of small and isolated groups with high but variable levels of inbreeding, and episodes of interbreeding with other Paleolithic hominins. It is reasonable to expect that high levels of endogamy could be expressed in the skeleton of at least some Neandertal groups.

   

• A Y Chromosome Census of the British Isles

  By analyzing 1772 Y chromosomes from 25 predominantly small urban locations, we found that different parts of the British Isles have sharply different paternal histories; the degree of population replacement and genetic continuity shows systematic variation across the sampled areas.

   

• Analysis of the Preserved Amino Acid Bias in Peptide Profiles of Iron Age Teeth From a Tropical Environment Enable Sexing of Individuals Using Amelogenin MRM

  We describe the first dental proteomic profiles of Iron Age individuals (c2000‐1000 years B.P), collected from the site of Long Long Rak rock shelter (LLR) in northwest Thailand.

   

• Have Europeans Always Arrived from the Near East? | Adventure Diffusion

  In 2015, a widespread group of geneticists (Mathieson et al. 2015) reported the first ancient DNA investigation of the full genome from 26 Anatolian skeletons, concluding that these belonged to a population that was the source of Europe’s first farmers.

   

• Expanding beyond the current core STR loci: An exploration of 73 STR markers with increased diversity for enhanced DNA mixture deconvolution

  Current approaches to mixture deconvolution of complex biological samples at times do not have the capability to resolve component contributors in DNA evidence. Additional short tandem repeat (STR) loci were sought that may improve the forensic genetic analysis of mixtures.
