Peace of Mind Male Lineage DNA Test kit
Legal DNA Test kit

The GTL Y–STR Male Lineage DNA Test determines whether or not two or more males are related by their paternal lineage. The Y chromosome has a comparatively infrequent mutation rate and therefore remains the same through many generations when it is passed on from father to son.

Diagram of YSTR Relationships

This DNA test focuses on the Y chromosome and produces a unique Y-STR DNA profile for each tested male. It is very important to note that this DNA test will not distinguish between males of the same paternal lineage.

For example: a male “A” and his alleged half brother “B” know they have different mothers but would like to find out if they have the same biological father. If the Y-STR DNA profiles produced by the Y-STR male lineage DNA test are the same then it is practically proven that they share the same biological father. If the Y-STR DNA profiles do not match then they do not share the same biological father.

The chart to the right illustrates other circumstances in which a Y-STR male lineage DNA test can be used.

If you have any questions regarding the additional costs of testing more than two males please email us or call one of our Customer Service Advisors on 0333 300 3130.

IMPORTANT NOTE: This DNA test can only be used for males. When testing male and female siblings to determine whether or not they share a common father, a Sibling DNA Test should be used. Please email us or call one of our Customer Service Advisors on 0333 300 3130 for more information.
