Adaptation through natural selection is limited because it requires O the absence of mutations
O slow rates of reproduction
O low genetic diversity
O genetic traits to exist in a gene pool
O traits that cannot be inherited

genetic traits to exist in a gene pool

Explanation:

Adaptation through natural selection is limited because it requires that the genetic traits must have existed in the gene pool.

Natural selection only acts on the existing gene pool and selects for adaptive genes, not that it creates new genes. Hence, for a population to be able to adapt to a particular change in the environment, the adaptive genes must have been present in the gene pool of the population. This, thus, makes adaptation through natural selection to be limited.
