Y Chromosome Testing
A Y-chromosome test (Y-STR test) is used to determine if males share the same paternal lineage.
The Y-chromosome is inherited and passed on from father to son. Since it has a relatively infrequent mutation rate, it will remain the same through many generations and is only broken by the birth of a daughter. However, if a direct male line can be concluded then all males in that direct male lineage will have the identical Y pattern; therefore, the Y chromosome can be used to test lineage in males.
Why would I need a Y chromosome test?
- If you need a paternity test but the father is deceased, the test may be used to test any of the males on his side of the family.
- If you and your siblings want to find out if you share the same father, it can be easier and more accurate to use the Y chromosome test.
- Male cousins can use it to see if their fathers were brothers or to check if they shared a common Grandfather through the paternal line.
- In immigration cases, one can use this test to prove a biological relationship between males sharing the same male lineage.
- This test can help in adoption cases where children grow up want to find their biological or “birth” families.
