The reduction in population caused reduction in variation of gene pool.

The population thus have small genetic variation.

The gene flow can only be increased by immigration or mutation

Bottleneck in cheetah is explained as narrowing of gene pool when large numbers of cheetah dies leaving small population with less genetic variation.

I believe the correct answer would be <span>variation. The definition of variation in biology means,</span><span> any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials. So i think that organisms can also be classified as variation. Hope this helped. ♥ ☺
