Are rare or common recessive deleterious alleles more rapidl

Are rare or common recessive deleterious alleles more rapidly reduced in frequency in a population via natural selection? Why?

Solution

Natural selection theory is given by darwin. Natural selection acts to preserve and accumalate minor advantageous genetic mutations. Suppose a member of a species developed a functional advantage(example it grew wings and learned to fly ). Its offspring would inherit that advantage and pass it on to thier offspring. The inferior (disadvantaged ) members of the same species would gradually die out, leaving only the superior members of the species. Natural selection is the preservation of a functional advantage that enables a specie to compete better in the wild.
