Final answer:
In DNA fingerprinting, the names of minutiae points labeled in a fingerprint key represent the unique patterns used to confirm if DNA samples are from related individuals. The child must share similarities with the fingerprint patterns of the parents to establish a genetic relationship.
Step-by-step explanation:
When information about the names of minutiae points labeled in a fingerprint key is sought, the investigation is centered on the unique patterns found within a person's fingerprint. These distinctive patterns, made up of ridges and lines, are critical to the process known as DNA fingerprinting. DNA fingerprinting is a technique that compares DNA samples to assess if they originate from related or unrelated individuals. If the DNA fingerprint of a child is to be established as related to that of the parents, there must be sufficient similarity in the DNA sequences that make up their respective DNA fingerprints.
This similarity suggests a genetic relationship strong enough to confirm familial bonds, due to the inheritance of these DNA fingerprint patterns from each parent. In practice, various technical approaches can be employed to generate a DNA fingerprint, and proper identification of these patterns is essential in forensic science, paternity testing, and other genetic analysis scenarios.
