About the Y chromosome
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 biological father without actually carrying out a paternity test. Carrying out a Y chromosome test with the alleged father’s male relatives can tell you if the tested individual’s share the same biological father.
This test will compare the Y chromosome profiles of the tested males. A full match between profiles confirms a shared paternal line. If the male siblings have different Y chromosome profiles then they do not share the same paternal line.
Other uses of the Y 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.
