Extended Family DNA Testing

Cousin DNA Tests and more

DNA Worldwide offers DNA testing for extended family relationships, such as 1st and 2nd cousins or great aunts and uncles.

While DNA test results for extended family relationships are not as conclusive as a DNA paternity test or other close relationship DNA test, they can support a distant biological relationship.

DNA Test for Y-chromosome (Male DNA) Comparison

For cousins or other distant relationships sharing a common paternal link. Results in 3-6 weeks. Includes 2 males with alleged common paternal ancestry.

£ 295.00 (inc. Vat)

DNA Test for mitochondrial (female DNA) Comparison

For cousins or other distant relationships sharing a common maternal link. Results in 3-6 weeks. Includes 2 individuals (male or female) with alleged common maternal ancestry.

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 line 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 0845 257 1217.

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).

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).
