All of the following are true of natural selection, EXCEPT A. it results in a change in allele frequencies over time. B. it works best in genetically uniform populations. C. it is the process by which evolution occurs. D. it results in some individuals surviving better and reproducing more than others. E. it results in populations better suited to their environment than their predecessors.

B.  it works best in genetically uniform populations.

Explanation:

Natural selection: The environment will determine which traits are used as and advantage to breed more successfully.

If every being of that specific species was exactly the same then natural selection would kill them all off at once.

If you had a zebra that was white and one that had stripes. the one with stripes would last longer.
