Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in West Asia, near present-day Syria, [1] around 20,000 to 25,000 years ago. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM).

Mar 22, 2023 · Haplogroup H is the most common mtDNA haplogroup in Europe. Approximately 40% of all people in Europe have a maternal lineage belonging to haplogroup H. It is widespread, but it is also a relatively new branch of the human family tree (Fig 1).

Only a few Jewish branchws are reported in the haplogroup H. The haplogroup H has two old subbranches: M2826 and P96. This first (H1) is a larger haplogroup that has a significant population in India and nearby countries. In Europe the Roma group has a shared ancestor in H1.

Mar 19, 2025 · Today, Haplogroup H is hugely prevalent in Europe, with approximately 40% of maternal lineages belonging to this group. It originated from Dravidian populations in Southern India and Sri Lanka and spread through predominantly Romani populations throughout the Paleolithic. Did you know?

Jul 19, 2024 · Y-DNA, on the male sex chromosome, is passed down from biological father to son, while mtDNA, or mitochondrial DNA, is passed from the biological mother to both the son and the daughter. When these DNA sequences are mutated, it causes a split in the evolutionary group, forming a new haplogroup.

Aug 25, 2015 · Haplogroups are genetic classifications or ancestral groupings within a population, typically defined by shared, inherited genetic markers or mutations. These markers are passed down from a common ancestor. They can be traced through the analysis of mitochondrial DNA (mtDNA) for maternal haplogroups and the Y chromosome for paternal haplogroups.

Mar 19, 2020 · Haplogroups follow male and female descendancy lines, with Y-DNA passing from father to son, and mtDNA passing from mothers to both daughters and sons. All haplogroups started as the original haplogroup in Africa, and as the many millennia have passed by, more and more haplogroups have come to be.

Women can link their accounts to a male relative on their father's side to receive a paternal haplogroup result. Understand your haplogroup's widespread migration patterns.

Haplogroup H (Y-DNA), also known as H-L901/M2939, is a Y-chromosome haplogroup. The primary branch H1 (H-M69) and its subclades is one of the most predominant haplogroups amongst populations in South Asia, particularly its descendant H1a1 (M52).

Apr 25, 2014 · Identifying your haplogroup can tell you a surprising amount about your deep ancestry. They are generally associated with particular geographic regions and can tell us about our ancestor's migration routes out of Africa, as well as linking you to a group of people who share ancient ancestors.
