Haplogroup Q-M25, also known as Q1a1b is a subclade or branch of human Y-DNA haplogroup Q-F1096 (Q1a1), which is, in turn, a subclade of Q-MEH2 (Q1a). In human genetics, each Y-DNA haplogroup constitutes a biological paternal lineages back to a shared common male ancestor.

Distribution edit
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.[2] Haplogroup Q is found in minority Turkmen tribes living in Afghanistan at percentages of about 32%,[3] and another study found that 42.6% of Iranian Turkmens have haplogroup Q-M25 (also known as Q1a1b).[4]
The Americas edit
Q-M25 has not been detected in pre-Columbian populations in the Americas.
Asia edit
Q-M25 has been detected in the Northeast of East Asia, in South Asia, and across Central Asia.[5][6][7] Though present at low frequencies, it may be one of the more widely distributed branches of Q-M242 in Asia.

West Asia edit
The frequency of Q-M25 varies greatly across West Asia. An extreme peak is seen in the Turkmen of Golestan.[4] 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.[8] 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.[9] 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.[10]

Europe edit
Q-M25 is present across modern Turkey[11] and in Eastern Europe.

Associated SNP's edit
Haplogroup Q-M25 is defined by the presence of the M25 Single Nucleotide Polymorphism (SNP) as well as the M143, L714, and L716 SNPs.
