In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by differences in the non-recombining portions of DNA from the Y chromosome (called Y-DNA). It represents human genetic diversity based on single-nucleotide polymorphisms (SNPs) on the Y chromosome.

Y-chromosome DNA Testing

​The main use of Y-chromosome DNA testing is to be able to confirm relations on the direct paternal line, and exclude people who are not related.

This test is perfect if you have reached a dead end on your direct paternal line.​ It is also great to try and find relatives if you happen to be adopted and are searching for your biological birth family.
