Eastern Black Sea DNA: What is Y-DNA? How can we describe the distribution of haplogroups in the world?

In this article I will present you information on the distribution of Y-DNA in the world. To be brief, Y-DNA is the chromosome found in male individuals that is inherited from father to son

without mixture and transfered from generation to generation without change except small mutations, thus which we can use to trace our paternal line.

Before I begin our articles, it will be in good taste to give you some info about the Y-DNA haplogroups, in other words, Y-DNA types in the world.

Haplogroup A: Originated in Africa and its various sub-branches are found in southern and central Africa.

Haplogroup B: Found in the southern, central and western parts of Africa.

Haplogroup C: Found in East Asia, Siberia and Central Asia.

Haplogroup D: Frequent in Tibet, the Andamans and Japan.

Haplogroup E: Spread in a wide geography spanning from Africa to West Eurasia, its sub-branches can give us clearer info.

Haplogroup G: Spread in a wide area, the Caucasus being in the first place, stretching all the way from Europe to Central Asia and South Asia in the South, we can learn geographic origins by looking at its sub-branches. Its G2 sub-branch is frequent west of the Caspian while its G1 sub-branch is frequent east of the Caspian.

Haplogroup H: Frequent in South Asia and among Gypsies.

Haplogroup I: Seen frequently in Scandinavia and the Balkans.

Haplogroup J1: Most frequent in the Arab geography and the Middle East.

Haplogroup J2: High in Anatolia, the Caucasus, South Europe and the Iranian basin.

Haplogroup K2 and P: Seen in Oceania (chiefly among Australian natives), East Asia and South Asia

Haplogroup L: Found in Iran, South Asia and the environs, one branch of it is found in the eastern Black Sea region.

Haplogroup N: Frequent among East and North Asian peoples.

Haplogroup O: High in East Asia.

Haplogroup Q: Found in high amounts in certain regions of Asia and among American natives.

Haplogroup R1a: An Indo-European-origined group found in eastern and central Europe, Russia, the Caucasus and Central Asia. The reason why we deal with R1 separately for its R1a and R1b sub-branches is that they are too widespread.
