Mitochondrial DNA
(mtDNA) has proven itself as an ideal tool for tracking
ethnic heritage. Inherited from the maternal genetic line,
mtDNA differs from nuclear DNA, because it changes very
little between generations; this unique attribute has
allowed scientists to use mtDNA for tracking as many as
hundreds of generations of genetic history. GeneTree’s
Ancestral Origins™ testing services harness this powerful
technology to help answer your questions regarding ethnic
background.
mtDNA in humans is distinguished by divisions into
clusters of ethnically similar individuals, called
haplogroups. These designations follow the matrilineal (i.e.
maternal line) history of humans, tracing the development
and movement of mankind, from its African origins to today’s
ethnic groups and their locations.
As a cutting-edge genetic technology, this use of mtDNA
in a genealogical setting is perpetually evolving. Since
developments arise often—even daily, GeneTree is dedicated
to providing the most up-to-date information possible.
The keys to understanding your haplogroup are the
differences noted under the “Haplogroup Assignment” section
of your report. As science uncovers new lineages and nuances
in the development of our deep ancestry, the keys will help
you decipher your own Ancestral Origins™.
This Fact Sheet is a summary of currently accepted mtDNA
haplogroups and their associated characteristics. Remember
that all lineages trace back to the originating “L” groups
in Africa. For the most complete picture of your deep
ancestry, use the accompanying table to trace your roots
from group to group to the genetic origins of the human
race.

A |
Haplogroup A originated in Asia approximately
60,000 years ago, and is currently represented
widely throughout Asia. It is through I2
subgroup that—along with haplogroups B, C, D and
X—the first native American populations emerged. |
|
B |
Haplogroup B is noteworthy as containing the B2
subgroup, which is among the five haplogroups said
to have born modern day Native Americans (along with
haplogroups A, C, D and X). B has its roots
50,000 years ago in Asia.
Quite notably, haplogroup B—unlike groups A, C, D
and X—has no representation among modern Siberian
peoples. |
C |
This haplogroup arrived approximately 60,000 ago.
Like CZ, this group also includes the Siberian
region of northern Asia,
and—along with A, B, D and X—is among the
haplogroups represented by native American
populations. |
CZ |
Haplogroup CZ is represented in today’s Eurasian
populations, occurring in northern and eastern Asian
locations, including the Siberian region. |
D |
This group, along with A, B, C and X, is said to
have spawned the native peoples of the Americas,
having emerged approximately 60,000 ago.
Haplogroup D includes individuals in both northern
and eastern Asia. |
E |
Very little is universally accepted regarding
haplogroup E. However, some representation of
its descendants is said to be found in
Argentina. |
F |
A descendant of Haplogroup R, this group is
represented in China and Japan, and is believed to have
arisen from eastern Asia. |
G |
Haplogroup G and its two subgroups (G1 and G2a) are
to be found in northeastern Siberia,
representing, among other groups, the Koryaks and
Itelmen peoples. The G haplogroup is also
common to the indigenous inhabitants of Kamchatka. |
H |
While common in the Middle East and northern Africa,
haplogroup H is ancestor to approximately half of
all European inhabitants; it is a prominent subgroup
of HV. |
HV |
Progenitor to groups H and V, this haplogroup
proliferated roughly 20,000 years ago, and accounts
for much of modern day western European peoples. |
I |
This group can be found in Mediterranean regions,
both in the Arabian and European centers. I
originated roughly 30,000 years ago, as one of the
first groups known to have yielded some of today’s
European peoples. |
J |
A descendant from JT, haplogroup J is found
prominently in Russia
and eastern Europe. It was born roughly 10,000
years ago, in—or near—Mesopotamia, and migrated into Europe. |
JT |
This haplogroup derives from R, and gave rise to
haplogroups J and T. |
K |
The Eurasian haplogroup K is thought to originate at
with European expansion that occurred circa 16,000
BC. Evidence of haplogroup K-descended
inhabitants has been recently uncovered in western
Europe. |
L1 |
This haplogroup is particularly significant in human
ancestry as it represents the group from which
all mankind is descended. Another
haplogroup, L0, preceded L1, but is long since
extinct. L1 is said to date back to 150,000
years ago, and can be currently found in West and
Central Africa, being common to the Khosian people. |
L2 |
L2’s African descendants represent roughly a third
of all sub-Saharan Africa,
having arisen from the L1 haplogroup approximately
70,000 years ago. This group is the most
common haplogroup among American blacks. |
L3 |
Another descendant of L1, haplogroup L3 is most
common in East Africa.
However, this group is said to have given rise to
the M and N (considered “macro-haplogroups”)
haplogroups, from which descend all of the world’s
non-African inhabitants. |
M |
This enormous macro-haplogroup finds its progeny
represented on various continents, having descended
from L3 approximately 80,000 years ago.
Haplogroup M is believed to have migrated into
Eurasia some 20,000 years later, populating southern Asia.
Its subgroups include M*, M1, C, D, E, G, and Z.
M is represented to some degree in modern day Pakistan. |
M1 |
This variant of haplogroup M is believed a result of
a migration swap, in which North Africans and some
Asians possibly returned to sub-Saharan Africa. |
N |
Another L3 branch, haplogroup N also spans the
continents, originating at approximately the same
time as its close relative, haplogroup M.
Haplogroup N’s significance lies in its ancestral
relationship to Europe’s
descendants. In fact, N is believed to have
spawned nearly all European haplogroups.
Haplogroups R, N1, A, I, W, and X, all descend from
group N. |
N1a |
N1a is traceable in inhabitants of Eurasia,
particularly those of Iran
and some Indian territories. The haplogroup’s
representation is limited to the flat, barren steppe
of western and central Asia. |
N1b |
The peoples of the Near and Middle East regions of
Asia can be found among N1b’s progeny. Scientists
have linked this haplogroup specifically with the
Jewish Ashkenazi peoples. |
Pre-HV |
Haplogroup pre-HV is widely represented in the
Middle East and parts of eastern Africa.
The ancestor of haplogroups HV, H and V, this set of
peoples is thought by scientists to have originated
near Arabia, subsequently reemerging in Africa.
|
Q |
The descendants of this haplogroup can be found in
the southern Pacific region, especially in
New Guinea and Melanesia.
Little is known about the group’s exact link with
its parent haplogroups. |
R |
A significant descendant of haplogroup of N, R’s
progeny can be found throughout both Asia and
eastern Europe, with representation from the Ural
mountains to Japan.
Groups B, U, F, HV, H, and V all descend from
haplogroup R. |
T |
Like its genetic sibling J, haplogroup T is thought
to have originated in Mesopotamia 10,000 years ago,
ultimately settling throughout eastern Europe,
making particular impact in the
Ural mountains and near the Baltic. |
U |
This group emerged some 55,000 years ago, and has
shown ancestral influence throughout Europe,
and contains the subgroups K, U1, U2, U3, U4, U5 and
U6.
Of its groups, the U5 cluster is notable as the
first exclusively European haplogroup, dating to
roughly 50,000 years ago. Some scientists
theorize that members of the subgroup U5a might have
encountered European Neandertals approximately
40,000 years before our time. |
V |
One of the later mtDNA groups, this haplogroup is
just 12,000 years old, thought to have been born in
or near present day Spain.
Its descendants are to be found among indigenous
peoples of Spain, as well as in some northern Scandinavian groups. |
W |
Found along the borders of Europe and Asia,
haplogroup W’s descendants are seen not only among
the inhabitants of the eastern Baltic and the Urals,
but in the population of India as well. |
X |
Today’s European population takes a moderate segment
of its people from the X haplogroup—more
specifically via its X2 subgroup, which is said to
have emerged circa 19,000 BC. The descendants
of X are represented widely from regions of
Russia to Mediterranean Europe and Israel.
Along with A, B, C and D, haplogroup X is
represented in the Americas’
indigenous peoples; however, unlike its siblings,
the group has no connections with eastern Asian
populations. X is instead to be found among
North America’s Ojibwa, Sioux, Nuu-Chah-Nulth,
Navajo, and Yakima peoples. |
Y |
With so little currently known about the relatively
small haplogroup Y, scientists have been unable to
emerge far beyond merely recognizing the group.
However, its descendants are said to be found in
eastern Asia. |
Z |
Another descendant of haplogroup M, Z derives
from central Asia. The diversity of this varied
haplogroup is represented everywhere from Korea and
China to Russia and Scandinavia. |
