Can DNA testing address genetic relationships other than paternity?

Yes. DNA testing provides general information regarding biological relationships. Thus, questions such as: “Are these two individuals related as full siblings or half siblings?”, “Are the twins identical or fraternal?” and “Do these two individuals share the same maternal lineage?” can be addressed. The amount of genetic information that can be obtained—and the likelihood of conclusiveness of such DNA tests—may vary from case to case. Consultation with our Director is therefore advised before scheduling an appointment for such DNA tests.
