[2025-10-01T23:54:42.079969] [PI reasoning] **Identifying chimerism impacts**

I’m considering the question about which scenario relates to the chimerism phenomenon. In forensic medicine, chimerism—having two genetically distinct cell lines—can complicate paternity testing since it may lead to inaccuracies. I remember a typical multiple-choice question from forensic textbooks stating that chimerism is linked with paternity tests, and it can cause false exclusions. So, I believe the answer would be “A. Paternity test.” I’ll verify this quickly with an evidence search.
