**Core Concept**
Fluorescence In Situ Hybridization (FISH) is a molecular cytogenetic technique used to detect and localize specific DNA sequences on chromosomes. It involves the use of fluorescent probes that bind to particular DNA sequences, allowing for the visualization of these sequences under a fluorescence microscope.

**Why the Correct Answer is Right**
FISH is a widely used technique for detecting chromosomal abnormalities, such as translocations, deletions, and amplifications. It is particularly useful for diagnosing genetic disorders and cancer. The probes used in FISH can be designed to target specific genes or regions of the genome, allowing for the detection of mutations or copy number variations.

**Why Each Wrong Option is Incorrect**
**Option A:** This statement is incorrect because FISH can detect deletions, duplications, and amplifications of specific DNA sequences, making it a powerful tool for genetic analysis.
**Option B:** This statement is incorrect because FISH can be used to detect chromosomal translocations, which are a common feature of many types of cancer.
**Option C:** This statement is incorrect because FISH is a quantitative technique, allowing researchers to measure the copy number of specific genes or regions of the genome.

**Clinical Pearl / High-Yield Fact**
FISH is a valuable diagnostic tool for detecting chromosomal abnormalities in cancer patients, and it can also be used to monitor the response of cancer to treatment.
