About the Y chromosome test
A Y chromosome test (Y-STR test) is used in cases where alleged male relatives wish to confirm they share a common paternal line. All male children inherit their Y chromosome from their father; these children will in turn pass the Y chromosome inherited from their father to their children when they become fathers.
This inheritance pattern means that males coming from the same paternal line will always share the same Y chromosome. Furthermore, the low mutation rate of the Y chromosome makes this test all the more reliable.
The Y chromosome is only found in males. Females do not have Y chromosomes. This means that although females cannot directly carry out a Y chromosome test, they can ask a male, paternal biological relative to take the test on their behalf.
When would a Y chromosome test be needed?
A Y chromosome test can help confirm if individuals share a common paternal lineage.
This test will compare the Y chromosome profiles of the tested males. A full match between profiles confirms a shared paternal line. If the males have different Y chromosome profiles then they do not share the same paternal line.
Other uses of the Y chromosome test include male cousins who can use this test to see if their fathers were brothers or to check if they shared a common grandfather or ancestor. In Immigration cases, the Y chromosome test can be used as proof of relationship but this requires a legal test. For further advice call our expert team on 0333 600 1300.
