Answer: Sexual reproduction
Explanation:
First, you should understand that mutation (an change in the base-pair sequence of the genetic material, DNA) is the original source of all genetic variation; as such whatsoever will alter the frequency of alleles, even if it is evolution, it relies on mutation.
In contrast, sexual reproduction does not change the frequency of alleles in the gene pool, rather it ensures constancy through the meiotic cell division process

Answer:
Half a billion to 14 billion.
Explanation:
The correct answer is - A. A mutation that causes the code for the wrong amino acid.
The missense mutation is a type of mutation that affects the amino acids of the organisms. This mutation results in a codon that codes a different amino acid rather than the one that should be coded. Because of this it causes a synthesis of a protein with altered amino acid sequence during translation. This type of mutation is basically a change in one DNA base pair that results in the substitution of one amino acid for another one.
