G-banding can detect large chromosomal abnormalities, FISH targets smaller DNA sequences within chromosomes, comparative genome hybridization can detect copy number variations across the genome, and allele-specific oligonucleotide hybridization is used for detecting very specific, often single-nucleotide, mutations or variations.
