Siblingship testing from DDC can help two alleged siblings verify whether they are full siblings or half siblings. A sibling DNA test is often performed when an alleged father is unavailable for a paternity test and his possible children would like to know if they have the same father.
DDC offers two types of sibling DNA tests:
Siblingship tests require complex DNA analysis. For this reason, we encourage the alleged siblings' mother(s) to participate in the testing whenever possible. The mother(s)' participation helps us eliminate the maternal contribution to the children's DNA profiles. This, in turn, helps us focus our analysis on whether the alleged siblings' remaining DNA could have come from the same biological father.
