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.
They both decrease genetic variation
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.

TRue
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.

Human recombination is a significant source of genetic variation.
