we know now that many genes have at least two forms, or alleles.
No.
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
There is a vast amount of variation in nature, as organisms are subject to genetic mutations, environmental influences, and natural selection. This variation allows species to adapt to different habitats and ecological niches, promoting biodiversity and resilience in ecosystems.

No, natural selection works on that genetic variation presented to it.
No.

They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
Yes...
