Haplogroup T (Y-DNA)
In human genetics, Haplogroup T-M184 is a human Y-chromosome DNA haplogroup. From 2002 to 2008, it was known as Haplogroup K2.
The UEP which defines this clade is generally considered to be the single nucleotide polymorphism (SNP) M184. Other SNPs (M272, PAGES129, L810, L455, L452, L445) are currently considered to be phylogenetically equivalent.
