Q-M25 has
descendants in modern populations across all of Eurasia. Only one detailed study on the Y-DNA on Turkmens from
Turkmenistan has taken place. Haplogroup Q is found in minority Turkmen tribes living in Afghanistan at percentages of about 32%, and another study found that 42.6% of Iranian Turkmens have haplogroup Q-M25 (also known as Q1a1b). Though present at low frequencies, it may be one of the more widely distributed branches of Q-M242 in Asia.
West Asia The frequency of Q-M25 varies greatly across
West Asia. An extreme peak is seen in the
Turkmen of
Golestan. Across the whole of Iran it varies from over 9 percent of the population in the north to only 2 to 3 percent of the population in the south. The frequency of Q-M25 drops to only about 1 percent of the population of
Lebanon's Muslims, and it is absent from the non-Muslim population there. However, its presence in the
Marsh Arabs(related to
Sumer) of Iraq hints that Q-M25's
West Asian history extends beyond a single localized recent founder.
Europe Q-M25 is present across modern
Turkey and in
Eastern Europe. == Associated SNP's ==
