  • Y-DNA haplogroups

    Y-DNA haplogroups are groups that share a common ancestor having the same single nucleotide polymorphism (SNP) mutation. Unlike mtDNA , which is passed down the matrilineal line, Y-DNA is passed solely along the patrilineal line, from father to son. Y-DNA can provide insight into both recent genetic ancestry via short tandem repeats (STRs) and ancient human migratory patterns via SNPs. Haplog...

  • DNA Testing: Choosing a test

    Genetic genealogy is a hot topic, but many people are put off by the learning curve. This is a place to get answers to your questions. MH/Geni DNA Tests This project is sponsored by Geni's curators to provide help in choosing a DNA test and understanding what questions the different types of tests might answer. How to participate If you want to see the discussions from thi...

  • R-U106 (Y-DNA)

    This project is for people who have tested and been assigned the paternal haplogroup R-U106 (Y-DNA) and also for people who are believed to have been this paternal haplogroup based on tests done on descendants. The current naming convention is to use the terminal SNP, so R1b, U106* Also known as R1b1b2a1a (S21+), previously known as R1b1b2a From The R1b1b2a1 (S21+) is a prominent R1b subcla...
