Mother and daughter generation times

Using time lapse microscopy, it is possible to record the generation times of individual mother and daughter cells. For a mother cell, the generation time is the time between successive budding events. For a daughter cell it is the time from when the daughter separates from the mother until its own first daughter is produced. When daughter cells first separate from the mother they are smaller than the mother and increase further in size before budding begins. Consequently daughter generation times are longer than mother generation times.

These data were recorded using cells of the strain ???? growing in medium that did not contain GdnHCl

For this particular data set, the differences are quite small - on average daughter cells take approximately 12 minutes longer than mother cells to reproduce. Other data sets show larger differences.
