Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG does its best to keep the tree updated with the latest developments in the field. The viewer may observe other versions of the tree on the Web. Email Ray Banks if the differences need clarification or if you find any broken links on this page.

The criteria for a representative SNP printed in bold for a subclade is: traditional usage, testing one in multiple labs, and/or being found in the area of the chromosome used in recent research studies.
SNPs listed below in italics (colored black or red) are quality variants from next-generation sequencing reports consistently showing as representing that subgroup.

Y-DNA haplogroup K is an old lineage established approximately 40,000 thousand years ago whose origins were probably in southwestern Asia. K's structure is interwoven with other haplogroups downstream (refer to the main tree at Y-DNA Haplogroup Tree). The subclades restricted to K itself are found at low frequencies in various parts of Africa, Eurasia, Australia and the South Pacific.
