Why Would You Want to Have Your DNA Tested?
1. To track the paternal line (Y-DNA testing). This test is for males only and is patrilineal.
2. To determine Y-DNA Haplogroup. Helps us to understand the historic migration patterns of our paternal
male lineage, and how our particular Y-DNA Haplogroup fits into human history. Male testing only.
3. To track the maternal line (mtDNA testing). This matrilineal test can be done for males and females.
4. To determine mtDNA Haplogroup. Helps us to understand the historic migration patterns of our maternal
female lineage, and how our particular mtDNA Haplogroup fits into human history. Males and females
can be tested, but the results pertain only to the maternal female line.
5. To determine genetic history , one’s general family origins, (Autosomal DNA testing) often reflecting premigration
times. These tests are also used to predict genetic distribution. As many ethnic groups have
been involved in multiple migrations, and some groups have been partly or completely assimilated into
other groups, this makes the genetic distribution results of these reports often quite confusing to those
who aren’t completely aware of the migration history of their ancestors, and who often identify with the
more recent perceived national or ethnic identity.
6. To determine relationships between two people, or the lack thereof.
A. Avuncular Test—Find out if two people are aunt/uncle and niece/nephew.
B. Grandparentage Test—Find out if two people are grandparent and grandchild.
C. Legal Paternity Test—Determines if the alleged father is truly the father for purposes of presenting
proof to a court.
D. Personal Paternity Test—Determines if the alleged father is truly the father for personal purposes.
E. Sibling Test—Find out if two people are siblings.
7. To comply with judicial order or legal requirement to compare the results of a DNA test to the US Federal Bureau of Investigation’s CODIS (Combined Data Index System) and NDIS (National Index Data System, part of CODIS) databases to ascertain identity and the existence of prior criminal activity.
