Can Neutral Alleles Evolve Through Selection? History. The neutral theory of molecular evolution contends that at the molecular level, most evolutionary changes and polymorphisms within species are not caused by natural selection, but by random genetic drift. How does neutral mutation affect evolution? Neutral mutation and the neutral theory of molecular evolution are not separate
Which Mutation Would Be Most Likely To Have The Least Effect On The Functioning Of A Protein? Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of
Can Neutral Alleles Evolve? Can neutral alleles evolve? Finally, one point that is often not fully appreciated is that neutral evolution can ultimately contribute to phenotypic evolution and to species adaptation. Kimura noted that many gene duplications may get fixed by random genetic drift, simply because they are not deleterious . What happens to neutral
