Familial DNA

Familial DNA refers to genetic information inherited from close relatives, such as parents or siblings. When forensic scientists analyze DNA found at a crime scene, they can compare it to known DNA profiles. Even if the DNA isn’t a direct match, it may share significant similarities with a suspect’s family members. By studying these genetic connections, investigators can narrow down potential suspects or identify individuals indirectly, especially when a direct match isn’t possible. This approach relies on understanding genetic inheritance patterns to link individuals through their familial relationships.
