What is the Arab haplogroup?

The most abundant haplogroups in Saudi Arabia, J1-M267 (42%), J2-M172 (14%), E1-M2 (8%), R1-M17 (5%) and K2-M184 (5%) are also well represented in other Arabian populations (Table 1). Precisely, in addition to Yemen, Saudi Arabia has significant haplogroup frequency differences only with Qatar (p = 0.009).

Is Haplogroup K rare?

Haplogroup K is found in approximately 13.213% of native Americans and Spanish . Overall the mtDNA haplogroup K is found in about 6% of the population of Europe and the Near East, but it is more common in certain of these populations. Approximately 32% of people with Ashkenazi Jewish ancestry are in haplogroup K.

How common is haplogroup J2?

Haplogroup J2 is carried by 6% of Europeans and its frequency drops dramatically as one moves northward away from the Mediterranean. Sephardic Jews have roughly twice as much J2 as J1 and Ashkenazi Jews have a near equal proportion of J1 and J2 haplogroup markers.

What is the difference between J1 and J2 haplogroup?

Of the two main sub-groups, J1 takes up four-fifths of the total and is spread widely on the continent while J2 is more localised around the Mediterranean, Greece, Italy/Sardinia and Spain. There is also limited evidence that the subclade J1 has long been present in Central Asia.

What is the oldest haplogroup?

A is the oldest of all Y-DNA haplogroups. It originated in sub-Saharan Africa over 140,000 years ago, and possibly as much as 340,000 years ago if we include haplogroup A00. Modern populations with the highest percentages of haplogroup A are the Khoisan (such as the Bushmen) and the southern Sudanese.

Where did haplogroup j2 originate?

In human genetics, Haplogroup J-M172 or J2 is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-M304….

What does Y DNA tell you?

The Y chromosome makes a genetic distinction between males and females. It is also called a “sex chromosome” because it determines whether a child will be biologically male or female. Although not as definite as a paternity test, you may be able to use Y DNA test to find a father.

Where is j2a4a found in the Middle East?

M47 The J2a4a subclade is found at low levels in Anatolia (1-4%) and Georgia (2%). In the Middle East, it has been detected at similar levels in Iran, Iraq, Qatar and the United Arab Emirates. This appears to be a relatively low frequency J subclade.

Where does the J2 haplogroup come from?

TMRCA estimates for this haplogroup range from 4-15kya. J2 may be an important Y-chromosome lineage that was part of the demic diffusion and introduction of new agricultural practices into Europe from the Middle East and Anatolia during the Neolithic period.

What was the purpose of the J2 chromosome?

J2 may be an important Y-chromosome lineage that was part of the demic diffusion and introduction of new agricultural practices into Europe from the Middle East and Anatolia during the Neolithic period.
