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 South African Progenitor is the first man on that line who arrived in SA.
To collect all our Y-DNA PROGS' profiles, with a list of their Geni user descendants. Below, please add your South African Y-DNA PROG if you can trace him back to his arrival in SA on the Geni tree. Alternatively if you know him from genetic testing and he is on the tree.
- you do need to first be a collaborator or collaborating with a collaborator- so please join the project using the request link under "actions" at the top right of the page. Visit Geni Wikitext, Unicode and images which gives a great deal of assistance.
TIP: If you know your Y-DNA Progenitor, Jeff Gentes' wonderful History Link App provides a way to check if there are others on the Geni tree who share him with you: + 'Ancestor Graph' ( top right) + Little boxed face in the middle, next to your name, & change the person to your Y-DNA PROG's profile link + Change the box options below to '15 Generations to Display'; 'Descendants' & 'Y-DNA' + 'Build Graph' (green box, top right) + Choose the 'Status' circle option - as this will show you which of his descendants are also Geni users (claimed profiles)
