The Y Chromosome Test can even be used to verify a different relationship between any two males in the same family (although always following the same paternal line), even if the alleged relationship is more distant. For example, a test between uncle and nephew, or a test between cousins.
Men have one Y chromosome and one X chromosome (while women have two X chromosomes and no Y chromosome).
The Y chromosome is inherited from father to son, as shown on the picture.
This means that all sons of the same father will present the same Y chromosome. Those sons will also pass that Y chromosome to their male children, so that grandfather and grandsons will also share that same Y chromosome.
However, it also means that, as all men in the same family have the same Y chromosome, this test cannot pinpoint the exact relationship on the individuals tested. And it also means that this test cannot be done when the individuals to test may have a blood relationship on the paternal side other than the one they seek to verify with the test.
The price indicated above is the final price for the analysis of 2 people with standard samples.
If you are unsure about whether this test is the best testing option for your case, please contact us. Please remember that, if there is a blood relationship between the fathers/mothers, this analysis may not be the adequate procedure for you; please, contact us before ordering your kit.
We can test other types of biological samples if you cannot send a mouth swab. Send us an email requesing a list of the non-standard samples we currently accept.
If you are in a big hurry, and can't wait for the kit to be mailed to you, you can download the paperwork for your DNA test. Fill in the forms and mail in samples taken by a cotton bud.
