Ancestry DNA Tests – Understanding Haplogroups in Ancestry DNA Tests

Ancestry DNA tests can reveal which haplogroup you are part of. This is quite useful and important knowledge in the study of genealogy, as it can provide you with knowledge of the geographical location where your very first ancestors originated from. Though it sounds like a very technical and complicated word, haplogroups are relatively easy to understand when explained methodically in simple terms. In this article I'll attempt to do exactly that, so that you can understand and appreciate the value of haplogroups and why they are included in the results of ancestry DNA tests.

What are the Haplogroups in Ancestry DNA Tests?

Basically haplogroups are the branches of the family tree for the entire Human race. Just as your family tree will have various branches for different lines of your family, the family tree of the human race does also. The haplogroups are based on the theory that particular populations of people originated in specific geographical locations on the earth, and then migrated at various times during the course of history. Through the application of Ancestry DNA tests, scientists have discovered specific haplogroups that originated in Europe, Asia, Polynesia, the Americas, Africa, and even specific ethnic groups like the Aboriginals of Australia. Every male in the world can be placed in one of these haplogroups by ancestry DNA tests that analyze DNA for a rare mutation that occurs on the male Y chromosome. There are over 40 known haplogroups associated with Y chromosome DNA.

There are in total 43 Y-Chromosome male haplogroups and 25 mtDNA or female branches that have been identified by Ancestry DNA tests. Some of the most popular Male haplogroups are;

1. Haplogroup A y-Adam. This is the most widespread of male Y chromosome branches and dates back nearly 60,000 years. It is believed that this was the original branch of the human race, hence it’s name A y-Adam. Most of the people in modern times that have been identified as part of this group by their ancestry DNA tests live in the Sudan, Ethiopia, and some regions in the southern half of Africa.
2. Haplogroup C. This group has been traced by ancestry DNA tests to having originated in the southern part of Asia around 50,000 years ago. It is found in populations of the south Pacific Islanders, mainland Asians, and to a small degree in some Native American Indian populations, furling speculation that those particular Native Americans found their way to mainland America from Asia and the Pacific. Findings like these are what make ancestry DNA tests so valuable to genealogists and mankind in general.
3. Haplogroup I, I1A and I1B. These three Haplogroups are found in people of Northern European descent, the Balkans, and those from the Iberian Peninsula area (Spain and Portugal). The first two were predominant among Scandinavian and Viking populations, while ancestry DNA tests have found markers from the third group – I1B in the Balkan and Slavic populations of Eastern Europe.
4. Mitochondrial Haplogroup H. This is one of the largest female branches uncovered by ancestry DNA tests, and is believed to have originated in Europe nearly 50,000 years ago. This is an extremely popular haplogroup discovered during ancestry DNA tests, with nearly 40% of all European females containing its markers.

As you can see, the haplogroup that ancestry DNA tests may put us in is quite important to understanding and fully appreciating our ancestry. Genetic ancestry testing takes us a bit deeper into our family history, not just illuminating our place in our own personal family history, but our place in the family tree of the entire human race. Ancestry DNA testing continues to be refined and researched, and who knows what we may be able to find out in the future. One thing for certain is that ancestry DNA tests can yield extremely interesting and undeniably useful information regarding our pasts, and possibly our futures as well.
