Y Chromosome DNA Testing

Y Chromosome DNA Test - Testing alleged MALE relatives to see if they share the same paternal lineage.

A Father's Y chromosome is passed down to his sons. This means that his sons will also have the exact same Y chromosome. If their Y chromosome was different, they would not share the same father. When organising this test you have to consider that two men with the same Y may not be brothers, they could be an Uncle and nephew or perhaps cousins. The Y chromosome test identifies if they share the same male ancestors or male lineage of the family.

So why would you order a Y chromosome test?

When the alleged father is not available for testing and the alleged relatives who want to be tested are male donors (women do not carry the Y chromosome).

Maybe you will consider ordering this test if

• Two brothers who want to know if they share the same biological father but there father is not available for testing.
• A brother of the alleged father is available for testing and wants to know if he is related to the child donors.
• You may be researching your family history and would like to firstly establish if two male donors are related.
• The paternal grandfather would like to know if he is related to his grandson when the child's alleged father is not available for testing.
