Called haplogroup J, it may improve mitochondrial function, protecting cells from aging and decreasing the risk of conditions such as Parkinson’s, dementia, or cancer.

You can think of each haplogroup as a separate branch of the human family tree.

If you upload raw data from National Geographic’s Geno project, you can also get Family Tree DNA’s estimates of your ethnicity and its haplogroup information at no charge.
