Autosomal DNA STR Marker Test for DNA Reunion
STR markers in Autosomal DNA are used for DNA relationship testing (such as paternity testing, sibling testing, etc.). Autosomal STR markers can be used to search the DNA Reunion database to find potential immediate family members.
Autosomal DNA is passed down equally from the father and mother to their child. STR markers in Autosomal DNA are used for DNA relationship testing (such as paternity testing, maternity testing, sibling testing, etc.). Autosomal STR marker testing (also commonly known as "DNA fingerprinting") is also commonly used for identification (i.e. missing person cases) as no two individuals have exactly the same Autosomal STR profile. Autosomal STR markers do not carry significant ancestry information. However, it can be used to confirm relationships between immediate family members. This marker can be used to search the DNA Reunion database to find potential immediate family members.
What is Autosomal DNA?
Autosomal DNA is the DNA which makes up Autosomal Chromosomes. Autosomal Chromosomes are found in the nucleus of most of the cells in our body. Both males and females have Autosomal DNA.
We are all unique
No two individuals who ever lived is the same... we are all unique. With the exception of identical twins, no two individuals have the same autosomal DNA profile. That's why autosomal DNA testing is also known as "DNA Fingerprinting".
How does this differ from mtDNA and Y-DNA?
All individuals who share the same maternal line will have the same mtDNA profile. That's because your mtDNA was inherited from your mother. Your siblings, your mother, your grandmother, your cousins and nephews and nieces and aunts and uncles on your mother's side of the family will all have exactly the same mtDNA profile as you. However, no two individuals, with the exception of identical twins will share the same Autosomal DNA profile.
Likewise, all males who descended from the same paternal lineage will have exactly the same or a very similar Y-DNA profile. That means that your Y-DNA profile will be the same as your brother's, your father's, your grandfather's and all other male descendents who shared the same paternal lineage as you. Again, this differs from autosomal DNA, as no two males, not even brothers, will have the same autosomal DNA profile.
Applications of Autosomal DNA STR testing
The unique characteristics of Autosomal DNA STRs make it a powerful tool for relationship and identity testing. Some of the most popular applications of Autosomal STR tests are as follows:
|Family Relationship testing|
|Paternity testing||To seek the biological father of a child, or to seek the biological child of a father.|
|Maternity testing||To seek the biological mother of a child, or to seek the biological child of a mother.|
|Full sibling testing||To seek the full biological sibling(s) of an individual.|
|Half sibling testing||To seek the half biological sibling(s) of an individual (same father only or same mother only).|
|Grandparentage testing||To seek the biological grandmother or grandfather of a child, or to seek the biological grandchild of a grandparent.|
|Aunt/Uncle testing||To seek the aunt or uncle of an individual on both the paternal and paternal lineage.|
|Nephew/Niece testing||To seek the nephew or niece of an individual on both the brother’s or sister’s lineage.|
|DNA Reunion Family searches||To search for immediate family using the DNA Reunion database.|
|Child Identification||To record your child’s DNA fingerprint as part of your child’s safety program. In the event that a child is missing, the DNA profile will assist law enforcement to find and positi identify the lost child.
|Personal identification||To record the personal DNA fingerprint of a family member for personal identification. TheDNA profile is a personal identifier for an individual and the identification can be attached to the family tree passed on to future generations. DNA fingerprinting can also be used to positively identify a family member during a disaster. Autosomal DNA testing was used for identification in a number of disasters, including 911, earthquakes, airline crashes and the US military.
|Record and preserve integrity of family tree||To record and preserve the integrity of the family tree. Every individual is connected in the family tree through a defined relationship type. This is enforced by the autosomal DNA profile and ca handed down to further generations as proof of integrity of the relationships defined in the tree. The DNA profile can be attached to the family tree and passed on to future generations as positive proof of relationship for future generations and to ensure ongoing integrity of the family tree, even after death. Proof of relationship generated through autosomal STR testing is a stronger proof of family relationships than even birth certificates.
|Matching and identification||To match the DNA found on a licked envelope, hair sample, or other forensic sample to an individual, whether living or deceased.|
DNA Reunion is an global database which allows people from around the world who have tested their DNA to search for potential close family members. One of the key features of DNA Reunion is that it is the world's first Autosomal STR database, and allows people to search for close relatives.
