  • South African Y-DNA - Male Progenitors

    Y-chromosome DNA (Y-DNA) is passed from father to son along an all-male line (highlighted in blue in the illustration below). Mitochondrial DNA (mtDNA) is passed from mother to child along an all-female line (See South African mtDNA Progenitors ). Males pass Y-DNA to their sons, but do not pass mtDNA to their children. Your Y-DNA-line is therefore your father's father's father etc; and your Y...

  • 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...

  • South African Genealogical DNA testing

    FamilyTreeDNA.com Projects The Cape Dutch Y-DNA Stamvader Project The South African mtDNA Project The South Africa Cape Coloured DNA Project We need to get as many SA people as possible to test both their Y-DNA and their mtDNA, for example via All it takes is a simple swab on the inside of your mouth. They will send you a kit. If enough SA people have it done, we could solve many ridd...

  • 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...

  • 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...
