Final answer:
Spectral karyotyping (C) is the technique among the provided options that is specifically used for detecting translocations in genetics. Southern blotting (B) and Comparative Genome Hybridization (E) are used for DNA sequence detection and identification of DNA sequence gains or losses, respectively.
Step-by-step explanation:
Translocations can be detected using several different techniques. However, among the options provided, Spectral karyotyping (C) is specifically designed to visualize genetic translocations. Spectral karyotyping uses fluorescent probes that are specific to different chromosomes, making it possible to see if sections of chromosomes have switched places.
Southern blotting is a technique where DNA fragments are transferred to a nylon membrane and hybridized with specific DNA probes to detect sequences in a genome. While Comparative Genome Hybridization (E) also can detect translocations, it is primarily used for identifying gains or losses of DNA sequences rather than specific translocations.
