The forecasts at that time of a population explosion had an adverse impact on the programme.

To determine the mean generation time of a population, the age of the individuals (x) is multiplied by the proportion of females surviving to that age (lx) and the average number of offspring left by females at that age (mx).

In S. cerevisiae two different paradigms are used to measure longevity: the replicative life span, which is defined as the total number of daughter cells generated by a mother cell; and the chronological life span which is measured by monitoring the mean/maximum survival time of a population of non-dividing yeast.
