Table 1 . Estimates of the mean number of generations (+/− SE) for each transfer period at the start of the MA experiment (i.e., for the ancestor) and for the two MA lines at the end of MA.

Transfer period (days)	Number of generations per transfer period

3	8.49 (0.41)
4	11.41 (0.44)	10.92 (0.37)	8.18 (0.48)
5	11.53 (0.84)	9.89 (0.24)	9.54 (0.46)
