Time dependence of the fraction of cells with zero to four chromosomes.

<p>(a) In the experiments (dots) and in the simulations (dashed lines) we start with 7 cells and determine the composition of the growing population. Cells without a chromosome (mini cells) are shown in blue, cells with one chromosome in green, with two chromosomes in magenta and with four chromosomes in cyan. (b) Comparison between the experimental data and calculated data obtained from averaging over 50 simulations each one starting with 1000 cells.
