Closely related species, like chimpanzees and humans, often differ in chromosome number by only one or two chromosomes, suggesting that chromosomes can experience fission and fusion over evolutionary time. Can you think of a way to test this?
What will be an ideal response?
Generate a karyotype for the species of interest and stain the chromosomes to obtain banding patterns. Compare the banding patterns of chromosomes that you speculate may be the product of fission or fusion–banding patterns are highly conserved–and you should be able to match up the chromosomes from one species with those of another.
