Beverly Crusher's DNA Scanner
A compact handheld medical device used by Dr. Beverly Crusher to collect DNA samples for genetic analysis. In the Observation Lounge, Crusher offers it to Ishara Yar for a quick DNA scan to verify her biological relationship to Tasha Yar, with the senior staff (Picard, Riker, Data, and Troi) observing. Later, in sickbay, Crusher uses the same device to brush its sensor against Ishara Yar's arm, capturing genetic data for direct comparison with Tasha Yar's DNA profile. Data confirms the sisters' biological link through this scan, amid crew debates over Ishara's loyalty.
