Answer:
Polygenic.
Explanation:
A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes".
Variations are important to natural selection because if every species was the same and natural selection did not like them that whole species would go extinct, if there is a variety of that species it will serve because natural selection will only take out the type of that species it does not like, for example sharks! There are many types of sharks. If all sharks where put into fresh water and they where all the same type they would all die but since there is a variety the sharks that can live in fresh water live and the ones that don’t die.

<span>The correct answer is A) a single amino acid may have more than one codon that translates for it.</span>
<span>This property of the codon is called codon degeneracy and is the redundancy of the genetic code. As a result, there is the multiplicity of three-base-pair codon combinations that specify an amino acid and that increases tolerance to point mutations (synonymous mutations). Usually, the codons encoding one amino acid differ in the second or third position.</span>
