describe an environmental factor that could influence natural selection and decrease genetic diversity. pick…

Brief Explanations:

One environmental factor is habitat loss. When a species' habitat is destroyed, like deforestation for the Amazon rain - forest species. Many organisms lose their homes. Only those that can quickly adapt or migrate may survive. For example, certain tree - dwelling frogs in the Amazon may perish if their tree habitats are cut down. This reduces genetic diversity as many individuals die and only a small, possibly less genetically diverse, subset may survive.

Answer:

Habitat loss. For instance, deforestation in the Amazon rain - forest reduces the habitats of tree - dwelling frogs, decreasing their genetic diversity as many individuals die.
