generally seem to be, the change in gene frequency will be very small in each
generation.

Thus among a series of initially identical colonies (bean bags) that all started with
the same gene frequency /), the mean gene frequency after one generation is still
p, but the colonies vary to the extent p(l — p)l2N; and the smaller the colonies, ...

The effect of environmental variation on genetic variation may be even more
complicated than I have indicated. For example, there may often be a frequency-
dependent component to selection in a patchy environment. A dry-adapted plant
