• As chromosome instability refers to the rate that chromosomes or large portions of chromosomes are changed, there should be comparisons between cells, or cell populations rather than looking at cells individually in order to determine chromosome instability. These differences should be examined statistically as well. • The rates in the cell population being tested should be compared to a reference cell population.
