Uses of a Y chromosome test

A Y chromosome test is usually done under the following circumstances:

  • Male siblings wish to determine whether they share the same father but are unable to directly confirm this through a paternity DNA test.
  • To determine whether males share the same paternal line. Male cousins, uncles, nephews, grandparents may all be interested in such a test to establish a common paternal line shared between them.

A Y chromosome test will, as stated, establishes the existence of a common paternal lineage; however, confirming the exact type of relationship between male relatives is not possible with this test. Thus, we will not be able to distinguish whether the relatives tested are for example brothers, uncle and nephew, or grandfather and grandson.
