Volume growth and division statistics. (a) For each trajectory, we determined the mean and standard deviation of certain cell growth characteristics, starting at birth. These features were compared across each cell's; various generations as well as across all trajectories. (b) The time to complete each cell cycle shows a downward trend over the first few generations. (c) The G1 (red) and S (blue) growth rates remain constant over time. (d) The time spent in each phase decreases over the first few generations, although the majority of time during the early generations is spent in G1. (e) The size of cells increases linearly with generation, although a larger jump in size of ∼5% is observed between the first and second generations. (f) The percent of volume lost by a mother cell to its bud decreases on average for about five generations. (g) Finally, the fluorescence production rate is observed to increase over the first five or six generations, on average.
