The Siblingship DNA Test compares the DNA from a shared biological mother, the sibling in question, and one or more known full or half-siblings to determine the likelihood if the unknown sibling is a full sibling; half sibling or unrelated.
This test will reflect the likelihood of relationship.
HIGH LIKELIHOOD OF RELATIONSHIP INDICATES:
If the siblingship index is greater than 1.00, this indicates that the tested individuals are more likely to be true biological relatives. The higher the value of the index, the greater the likelihood that the individuals are true biological relatives.
LOW OR NO LIKELIHOOD OF RELATIONSHIP INDICATES:
If the siblingship index is less than 1.00, this indicates likelihood of non-relatedness.
**Note: When a known parent is not included in the Siblingship DNA Test, the test results may not always be conclusive.
