The projects in this index are automatically created by when a user uploads y-dna test results to geni. Y-dna passes from a father to his sons. When you upload a y-dna test results to geni it first copies the haplogroup designation to the profile of the male tested. Additionally it then copies the y-dna haplogroup name up to that man's father, and then his paternal grand-father and so on for up to 10 generations. Geni also copies the haplogroup designation down to all direct male descendants of these 10 paternal generations.You can learn more about y-dna haplogroups on geni by visiting this page: Y-DNA HaplogroupsFor and index of mt-dna projects visit here: mt-DNA Geni IndexFor an index of user generated dna related projects visit here: DNA Geni Index
