From an initial**
q = 0.50** in each of **20 **populations with either
**2N = 18** or **100
**starting individuals,
**q**** = f(A)** diverges at random over time from the
starting value, and the divergence in more rapid among smaller
populations than larger. Where **2N = 18**, several
populations reached either loss (**q = 0.0**) (n = 5)
or fixation (**q = 1.0**) (n = 7) of the allele in less
than 20 generations, whereas in the right-hand graph, all
populations maintain both alleles after the same time.
