Haplogroup Tree Mutation Mapper

From ISOGG Wiki

Haplogroup Tree Mutation Mapper is a feature of 23andMe's Personal Genome Service. It can be accessed from Ancestry Labs from the 23andMe user interface.

This feature shows which particular mutations in a person's mitochondrial DNA or Y chromosome were used to determine their haplogroup assignment.

The 23andMe Personal Genome Service uses thousands of single-nucleotide polymorphisms (SNPs) to describe hundreds of mitochondrial DNA and Y chromosome haplogroups. This experimental feature will tell which SNPs were used to define a given haplogroup. Just enter a haplogroup's name to retrieve the SNPs that were used to define it. The list begins with the mutation that defines that haplogroup's most recent branch on the mitochondrial or Y chromosome tree and works backward to the root. Because the Haplogroup Tree Mutation Mapper is an experimental feature in 23andMe Labs, it may not work as well or provide as much documentation as other supported features.
