The full form of CGH is Comparative Genomic Hybridisation.
According to the provided abstract, Comparative Genomic Hybridisation (CGH) is a technique used to identify chromosomal copy number changes without the need for cell culturing. It allows for a broad overview of chromosomal gains and losses throughout an entire tumor genome.
In summary, CGH is a valuable tool in genetics for detecting chromosomal abnormalities, particularly in cancer research.
