An example of generation counter internal state. Each species of the type Diff holds an internal state called Gen which holds the number of cell divisions since the differentiation event. The histogram of the Gen values over the entire population can be calculated at different time points (e.g. after 10, 50 and 100 days, shown in (A), (B) and (C) respectively).
