A sibling test determines whether two children share one or both parents.
Sisterhood testing is a DNA test carried out to determine if two children share one or both parents (eg, if they are half-siblings or siblings of a father and mother). It is an indirect way of determining family relationships when an alleged father is not available for a paternity test. The results of a sorority test can be used as evidence in insurance benefit claims and other inheritance claims.
The guild test can be done in several ways:
- Brother 1 and Brother 2 who do not share the same mother and want to find out if they share the same biological father, in this situation, a half-brotherhood test is carried out.
- Brother 1 and Brother 2 who share the same biological mother but are not sure if they share the same biological father, in this situation, a full sisterhood test is performed.
In the test, the DNA profiles of the siblings are compared to see how much of their DNA may have come from a common father. The mother’s participation is recommended to help exclude the mother’s contribution to the child’s DNA. Sisterhood tests require more analysis, and can be more expensive and take longer to complete without the mother’s involvement.
