Indicate whether each of the following descriptions better applies to an asymmetric (A) or a symmetric (S) stem-cell division strategy. Your answer would be a four-letter string composed of letters A and S only, e.g. AAAA.
( ) It predicts the number of stem cells in a population to remain strictly constant after several rounds of cell division.
( ) Cytoplasmic factors that control stemness are localized to one side of the cell before cytokinesis.
( ) It is a more flexible strategy and can better accommodate the effect of environmental factors.
( ) It is more consistent with observations in gut stem cells and other stem cells.

The symmetric strategy is more probabilistic and flexible. It is also more consistent with the observed division patterns of stem cells in the gut and elsewhere.
