| PATERNAL
TESTS
 Male—Y/CS25
Men pass their Y chromosome on to all of
their sons from generation to generation.
Historically speaking, all men descend from
a single man who lived 60-70,000 years ago
in Africa. Over time, his descendants branched
out into many families. Family Tree DNA
has the world’s largest comparative database;
they will test 25 markers on your Y chromosome
to determine which branch of the male ‘family
tree’ of mankind you are in. If your branch
cannot be confidently predicted, we will
perform the additional testing necessary
to determine it at no additional charge.
African Americans often share genetic
ancestry with more than one ethnic group
in Africa because of the fluid nature of
many of the groups. This reflects our rich
genetic ancestry in Africa and that, because
of migration and other factors, African
Americans are not limited in their genetic
heritage merely to one ethnic group. Migrations,
group conflicts, and wars made our ancestors'
DNA move across borders and between groups.
Only rarely will an African American match
a single ethnic group. Family Tree DNA informs
you of all of the ethnicities your paternal
lineage matches. This list will continue
to update and grow as more ethnic groups
are sampled in Africa.
We include a certificate and personalized
report with each order.
MATERNAL TESTS
 Female—mtDNA
Female inheritable mitochondrial DNA (mtDNA)
passes from the mother to all of her children,
and from her daughters to their children,
and so on in an unending genetic chain.
Therefore you and your mother's sister's
child have identical mtDNA.
Historically speaking, all people descend
from a single woman who lived over 120,000
years ago in Africa. Over time, her descendants
branched out into many families. In addition
to sequencing 1116 base pair region of your
mtDNA, Family Tree DNA can test you for
22 positions that identify which branch
of the mitochondrial ‘family tree’ of mankind
you belong to. The combination of these
results provides geographical matches when
compared against our database.
