YSTR Lineage DNA Testing | Your Unique Paternal Heritage is in your Genes | EasyDNA Nigeria

About our test

A Y chromosome test (Y-STR Test) is used to determine if males share the same paternal lineage. This test offered by easyDNA Ireland is highly accurate and will give a clear yes or no answer.

The Y chromosome is inherited and passed on from father to son. It has a relatively infrequent mutation rate and remains unchanged from generation to generation.  If a direct male line can be traced, all males in that direct male lineage will have identical Y chromosome patterns (if they are truly blood relatives). Important to note that only males can do a Y chromosome test. Females do not have Y chromosomes.

Why would I need a Y chromosome test?

  • In cases where paternity is in question and the alleged father is not available for a paternity test, a Y chromosome test between the alleged father’s child and another paternal male relative can solve the issue.
  • A Y chromosome test between male relatives can help confirm biological relationships as male blood relatives from the same paternal line will have a common Y chromosome pattern.
  • In Immigration cases, one can use the Y test to prove a biological relationship between males. A DNA test can help hasten immigration procedures under some circumstances.
  • In adoption cases, children grow up wanting to find their biological or “birth” families can use a Y test to confirm their relationship to their suspected biological father.
