FISH can be used to study the evolution of chromosomes. Species that are related have similar chromosomes. This homology can be detected by gene or genome sequencing but also by FISH. For instance, human and chimpanzee chromosomes are very similar and FISH can demonstrate that two chimpanzee chromosomes fused to result in one human chromosome. Similarly, species t… WebNormal chromosomes are recognized based on the uniform staining of entire chromosome compared with morphology using DAPI staining.
