Paternal Lineage DNA Test

Paternal Lineage (Y-STR) DNA Testing

Paternal Lineage (Y-STR) DNA Testing

Tracing your paternal lineage

Wanting to confirm a relationship with a possible male relative? The Y-STR Paternal Lineage DNA Test can show if there is a relation between two males.

The Paternal Lineage test only works on biological males. Due to the Y chromosome being hereditary and passed down from father to son relatively unchanged over time (females do not have a Y chromosome). This test is limiting in that it cannot pinpoint the exact relationship between the two males that share a common paternal ancestor. It only determines whether two males share the same paternal Y-STR marker. However, the test is helpful in excluding certain males from an alleged biological relationship.

If you are trying to prove the specific paternal relationship of an alleged father and son, please see our Paternity DNA Testing page.
