Y Chromosome DNA Test

The Y Chromosome is passed from fathers to their sons, and generally does not mutate much as generations pass. If a direct biological line can be established, then all males in that line will have identical Y chromosome data. The Y Chromosome DNA Test (Y-STR) is used in the absence of an alleged father’s ability to provide a DNA sample.

Y Chromosome

A Y chromosome test is generally used to link the tested males for shared paternal lineage; as the Y Chromosome is passed from generation to generation. A simple test that allows male relatives to determine the biological relationship.

This test is best for:

  • Confirming or excluding paternity by testing the alleged father’s male relatives
  • Immigration cases where, in the absence of a birth certificate or family book, the Y chromosome is tested to confirm a biological relationship
  • Brothers who want to know if they share the same father
  • Male cousins who want to know if their fathers were brothers
  • Adopted children who wish to gain information and reunite with their birth parents
