DNA Testing for Extended Family

Cousins and more.
IDENTIGENE offers DNA testing for extended family relationships in addition to DNA paternity testing. While DNA test results for extended family relationships are not as conclusive as a DNA paternity test or other close relationship DNA tests, they can support a distant biological relationship.
DNA TESTING FOR PATERNAL OR MATERNAL LINE COMPARISONS
When comparing paternal or maternal lineage, DNA testing examines Y-chromosome (Y-DNA) or mitochondrial DNA (mtDNA) profiles from two (or more) individuals. If the DNA profiles are an exact match, the tested individuals share a common link within four generations - and could be as closely related as siblings or cousins. If the profiles do not match, a close relationship, such as siblings, cousins, or aunt/uncle, is not possible.
Paternal and maternal line comparison results are not as informative for close relationships as other types of DNA relationship testing. DNA tests for Y-DNA or mtDNA comparisons, however, may be the only DNA testing option in some cases. For help with this and other types of DNA testing, please call 888-404-GENE (888-404-4363).
Y-Chromosomal DNA (Y-DNA)
Y-DNA appears in males only and always passes from father to son. Genetic genealogy primarily uses Y-DNA for surname studies, since Y-DNA corresponds to family names. Y-Chromosome DNA testing compares two Y-DNA profiles for a match (supports a close biological relationship) or no match (refutes a close biological relationship)
| Y-DNA Comparison Test | $495 |  |
|---|---|---|
| Includes 2 males with a possible relationship through their father's lines (paternal line relationship). Results available in 3-4 weeks from samples arriving at the laboratory. | ||
| Can these test results be used in Court? | ||
Mitochondrial DNA (mtDNA)
mtDNA appears in males and females and always passes from mother to child. Genetic genealogy primarily uses mtDNA for family group studies, where participants share common maternal ancestry. Mitochondrial DNA testing compares two mtDNA profiles for a match (supports a close biological relationship) or no match (refutes a close biological relationship).
| mtDNA Comparison Test | $495 | |
|---|---|---|
| Includes 2 individuals with a possible relationship through their mother's lines (maternal line relationship). Results available in 3-4 weeks from samples arriving at the laboratory. | ||
| Can these test results be used in Court? | ||
NOTE: While IDENTIGENE does not offer surname studies or other genealogical database services, we can compare two profiles for matches which support a close biological relationship.
