Document Summary
A change from one codons to another with the same amino acid is called a synonymous. Genetic diversity, the raw material on which evolutionary processes act, is generated by mutation and recombination. Mutation an occasional random chemical event can result in mutations, such as the replacement of one base with another, or the insertion or deletion of one or more bases, or even rearrangements of large regions of chromosomes. Although they do not kill the organism, they. Alleles that arise from synonymous mutations, which do not alter the amino acid are likely. Alleles that arise from advantageous mutations increase in frequency only because they one source of the many common allelic variants that are termed neutral" because. Mutations do not arise to ful l a function, nor do they re ect the intentions of individuals. Only synonymous mutations or very rare advantageous mutations would produce.
