Haplogroup Q-P89.1 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-P89.1 is defined by the presence of the P89.1 Single Nucleotide Polymorphism (SNP). In 2010, Q-P89.1 was reclassified as "private" and removed from the haplotree.
Q-P89.1 has descendants in the Northwest Territory of modern Canada. It was in pre-Columbian American populations that it was discovered.
Q-P89.1 is present in pre-Columbian populations in the Canadian Northwest.
Because samples from Asia have only sporadically been tested for this lineage, its frequency there is uncertain.
Q-P89.1 is currently defined by only the P89.1 SNP.
