Haplogroup Q-M242 is one of the two branches of haplogroup P-M45. Haplogroup Q-M242 is believed to have arisen in North Asia approximately 17,000 to 22,000 years ago.(In another source, 31,400YBP) It has had multiple origins proposed.pproximately 2% of males in Turkey belong to haplogroup Q. In a study by Gokcumen it was found that among Turks that belong to the Afshar tribe haplogroup Q-M242 is seen with a prevalence of 13%.
The alternative way of naming haplogroups is to refer to the SNP mutations used to define and identify them, for example R-M343 which is equivalent to R1b.. Haplogroup R1b is in other words now identified by the presence of the single-nucleotide polymorphism (SNP) mutation M343, which was discovered in 2004.From 2002 to 2005, R1b was defined by the presence of the SNP named P25.1b, R1b1, and so on are  phylogenetic  or family tree based names which explain the branching of the family tree of R1b. For example, R1b1a and R1b1b would be branches of R1b1, descending from a common ancestor.
