Sibling DNA Test

Service Description

The siblingship test determines whether or not two people share 1 or 2 biological parents. This DNA tests show the probability of siblingship between two people. In a full- versus half-sibling test, the DNA of two people with the same biological mother is compared to determine how likely they have the same alleged father. We also recommend that the biological mother of the alleged siblings also provide a sample. This helps us determine which genes came from the mother and which were contributed by the father. Having the mother's sample gives a big boost to the conclusive results. We can also compare two people's DNA with different mothers to find out if they have the same father. We prefer to have the DNA of the mothers to deliver conclusive results. If there are undisputed siblings, their buccal swab samples will also help us conclude. Options: 2 Alleged Full or Half Siblings without Common Parent 2 Alleged Full or Half Siblings with Common Parent 2 Alleged Half Siblings with each sibling testing their respective mothers *There is an extra fee to add on additional alleged fathers & children, please call us to discuss pricing.
