Relationship DNA Testing

Relationship DNA testing can be used to determine the existence of genetic relationships between potential relatives. The types of relationships tests can be done between any of the following: aunts, uncles, nephews or nieces, grandparents with their grandchildren or between siblings.

In most cases, relationship are carried out as a substitute for a paternity DNA test, or less commonly a maternity test where the alleged father or mother are not available for testing. In cases where the alleged parent is available for testing it is simpler to test them directly.

• Avuncular DNA Test: testing father’s relatives in order to establish paternity.

The following are the different types of DNA testing methodologies adopted in relationship DNA testing:

• The Short Tandem Repeat Test (STR test): This is normally done in cases where siblings tested are of a different sex and want to know if they share common parents.

• Y Chromosome Test: this chromosome is only found in males and thus, paternal lineage between male siblings or relatives can be determined using this type of test.
   
• X Chromosome Test: this test is used to establish whether two alleged sisters with different mothers share the same father.
   
• MtDNA Test (mitochondrial DNA): this test can establish whether two individuals, either male or female, share the same maternal line.
