Short Tandem Repeat Analysis

Full siblings and half siblings

Full siblings and half siblings of course share a lot more DNA in common than do unrelated persons. Of course half siblings do not share as much as full siblings. The purpose of this test is therefore to look at the amount of DNA shared in common and to apply statistical analysis to deduce the biological relationship.

Because the analysis is based on a comparison on common DNA, it is always best to submit the sample from any known parent/s of the person/s being tested. This will drastically help the evaluation process as it allows for a more accurate identification as we can then separate the maternal and paternal DNA of the individual being tested.
