In human genetics, 'Human mitochondrial DNA haplogroups' are haplogroups defined by differences in human mitochondrial DNA. These haplogroups trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread across the globe.
Known haplogroups are assigned the following letter codes:
A,
B,
C,
D,
E,
F,
G,
H,
HV,
I,
J,
K,
L1,
L2,
L3,
M,
N,
Q,
R,
T,
U,
V,
W,
X, and
Z.
The woman who is at the root of all these groups is the most recent common matrilineal (female-lineage) ancestor of all living humans. She is commonly called Mitochondrial Eve.
Evolutionary relationship
Precise evolutionary relationships between human mitochondrial haplogroups are subject to academic debate.
