Question

Quizplus · Accepted Answer

Multiple alleles are common because a gene sequence can vary in different ways and still encode a functional protein. This is due to the redundancy of the genetic code, where multiple codons can code for the same amino acid. Therefore, different variations of a gene can exist without affecting the function of the protein it encodes.
