DNA testing might be indicated in which of the following situations?

• A. a man involved in a paternity suit
• B. a person suspected in a murder
• C. parents who suspect they brought the wrong baby home from the hospital
• D. All of them

Answer: (D)

DNA testing is a tool for confirming biological relationships and identifying individuals. In a paternity case, it provides objective evidence about whether a man is the biological father. In a murder investigation, DNA analysis of crime-scene evidence helps identify a suspect or link him to the crime. When there’s a concern that a baby was swapped at birth, DNA testing can verify the infant’s biological relationship to the parents to confirm the child’s identity. Because it can serve each of these purposes, DNA testing may be indicated in all three scenarios. Of course, ethical and legal considerations like informed consent and proper chain of custody are essential to ensure the results are valid and used appropriately.
