A siblingship
test is a DNA test conducted to determine if two
children share one or both parents (i.e., if they
are half or full siblings). It is an indirect way to
determine family relationships when an alleged
father is not available for a paternity test.
Results of a siblingship test may be used as proof
in Social Security benefit and other inheritance
claims.
A siblingship test starts with the analysis of known
relatives:
Sibling 1 and Sibling 2 do not share the same mother
and they want to find out if they share the same
biological father—in this situation, a half
siblingship test is performed.
Sibling 1 and Sibling 2 share the same biological
mother but are unsure if they share the same
biological father—in this situation, a full
siblingship test is performed.
In the test, the siblings’ DNA profiles are compared
to see how much of their DNA could have come from a
common father. Participation of the mother(s) is
encouraged to help exclude the mother’s contribution
to the children’s DNA. Siblingship tests require
more analysis, and they could be more costly and
take a longer time to complete without the mother’s
participation.
