An example showing the calculation of Q i from the frequencies of all possible transit‐amplifying cell lineages for asymmetric and symmetric division and g = 3. Note that l A + l B + l C = 1 and l A + l B + l C + l D = 1 for asymmetric and symmetric division, respectively. Q i is calculated by summing, over all lineages, those i th generation cells that give rise to two post‐mitotic cells and dividing by the total number of i th generation cells.
