DNA Haplogroups Database

Trace your ancestry back over 100,000 years to its ancient roots in Africa.

In the study of the ancient ancestry of humans, scientists focus on “haplogroups”, the classification of all humans into ancient family clans based on the unique pattern of genetic markers called “SNPs” found their DNA. SNPs are small changes in the DNA which occur naturally over time. Once a SNP occurs, it becomes a unique lineage marker that is passed down to all future generations. Humans who have descended from the same ancient family clan will share the same pattern of SNPs.

Using SNPs, scientists have been able to plot the haplogroups of all humans living today into a single phylogenetic tree of mankind which shows how all humans are connected to each other in a complex worldwide tree that stems from Africa over 150,000 years ago.

Dozens of haplogroups have been discovered to date, each haplogroup representing a major branch in the phylogenetic tree of mankind.

Each haplogroup can be further refined into “subclades” (finer sub-branches of the tree). As new SNPs are discovered, the phylogenetic tree becomes increasingly detailed with finer branches and enhanced resolution. By testing individuals from around the world and analyzing their precise placement in the phylogenetic tree of mankind, scientists are attempting to piece together the intricate puzzle of ancient human connections and migrations.

How are haplogroups classified?

Haplogroups are named using capital letters of the alphabet (i.e. A, B, C…, etc.). Each haplogroup can be further subclassified into subclades. Subclades are named using numbers and lower case letters following the initial haplogroup letter (i.e. R1b1b2a2b1a is a subclade of haplogroup R).

2 Types of DNA Hold Clues to Our Ancestral Past

In human population genetics, the two types of haplogroups studied are Y-DNA and mtDNA haplogroups:

  • Y-DNA haplogroups (paternal ancestry)
    Y-DNA is inherited solely along the paternal line (father to son). The lineage traced is the father’s, father’s, father’s… paternal line.
  • mtDNA haplogroups (maternal ancestry)
    mtDNA is inherited solely along the matrilineal line (mother to child). The lineage traced is the mother’s, mother’s, mother’s… maternal line.

The DNA Ancestry Project allows people to test their DNA in order to predict or confirm which Y-DNA and mtDNA haplogroup they belong and to gain insight into their ancient ancestral origins.

The Y-DNA haplogroup can be predicted us Y-DNA STR testing, but the only way to confirm the Y-DNA haplogroup is through Y-DNA Backbone SNP testing. The mtDNA haplogroup can be predicted by testing the HVR-1 and HVR-2 regions. The mtDNA haplogroup and subclade is confirmed by testing the Coding Region in addition to HVR-1 and HVR-2.

DNA Reunion Database

DNA Reunion
DNA is a powerful way to connect family members. When the paper trail ends, DNA can provide strong leads for finding missing relatives and filling in gaps in your family tree. The DNA Reunion Database allows individuals who have tested their DNA markers to search for matches in an attempt to find close and distant family members.

Indigenous DNA Database

Indigenous DNA
The Indigenous DNA Database contains data from indigenous studies from published scientific journals around the world. Scientists are racing against time to document the DNA type of the world’s existing indigenous population groups. Individuals who have tested their Y-DNA SNP markers or mtDNA markers can compair their DNA against published markers of indigenous population groups.

DNA Haplogroups Database

DNA Haplogroups
Haplogroups are ancient family groups dating back tens of thousands of years. Individuals who have tested their Y-DNA or mtDNA can view their placement in the DNA Haplogroup Phlyogenetic tree of mankind. Read about what is currently known about the haplogroup that you belong to, see how your haplogroup diversified from its roots in Africa, and view the ancient migration pattern of your mtDNA or Y-DNA haplogroup within and/or out of Africa.

DNA Archaeology Database

DNA Archaeology
As mass graves are uncovered, preserved specimens are unearthed, and historical families are investigated, scientists are increasingly turning to DNA to solve unanswered questions regarding the origins, relationships and relevance of their discoveries. The DNA Archaeology database allows individuals who have tested their DNA to read about how DNA is used in archaeological discoveries and compare their genetic markers against published DNA sequences from ancient and historical individuals.
