• YFull Launches New mtDNA Tree

  As many of you know, Phylotree has not been updated in several years. While I support Phylotree and Dr. Van Oven’s efforts, he has not answered emails in some time either. This is so for both many of you and for myself.

   

• Genealogy & The Murder of Angie Dodge

  In some genetic genealogy circles, they call it the Usry Case. It should not be called that though. It is the ongoing investigation into the murder of Angie Dodge. Angie was 18. A few short weeks after she moved into her first apartment, she was found dead.

• 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.

  
   

• Peoples, Places, and Human History

  Human existence, our beginnings, trace back to Africa. For over a million years, we have traveled within and away from our homeland. Those travels have built upon one another and created our modern cultures.

  
   

• mtDNA Testing for Genetic Genealogy

  An mtDNA test (mitochondrial DNA test) is used for maternal genealogy. MtDNA is passed from a mother to her children. Thus, it traces a direct maternal line. Both men and women can take mtDNA tests.

• Phylogeography of Y-chromosome haplogroup Q1a1a-M120, a paternal lineage connecting populations in Siberia and East Asia

  We generated 26 new Y chromosome sequences of Q-M120 males and co-analysed 45 Y chromosome sequences of this haplogroup. We reconstructed a highly revised phylogenetic tree of haplogroup Q-M120 with age estimates.

   

• A Rare Deep-Rooting D0 African Y-Chromosomal Haplogroup and Its Implications for the Expansion of Modern Humans out of Africa

  Here, we re-investigate a rare deep-rooting African Y-chromosomal lineage by sequencing the whole genomes of three Nigerian men described in 2003 as carrying haplogroup DE* Y-chromosomes, and analyzing them in the context of a calibrated worldwide Y-chromosomal phylogeny.

   

• Molecular genealogy of Tusi Lu’s family reveals their paternal relationship with Jochi, Genghis Khan’s eldest son

  In this study, we surveyed the molecular genealogy of Northwestern China’s Lu clan who claim to be the descendants of the sixth son of Genghis Khan, Toghan.

   

• Palaeo-Eskimo genetic ancestry and the peopling of Chukotka and North America

  Here we present genomic data for 48 ancient individuals from Chukotka, East Siberia, the Aleutian Islands, Alaska, and the Canadian Arctic.

   

• Resolving a 150-year-old paternity case in Mormon history using DTC autosomal DNA testing of distant relatives

  Among all the children attributed to Joseph Smith Jr., Josephine Lyon, born in 1844, is perhaps the most frequently mentioned. In the current study, 56 individuals, mostly direct descendants of Joseph Smith Jr. and Josephine Lyon, had their autosomal DNA tested to verify Josephine’s biological paternity.
