If an amino acid has multiple triplet codes, the genetic code is described as:

Explanation:
The genetic code is redundant because an amino acid can be specified by more than one triplet codon. Since there are 64 possible codons but only about 20 amino acids (plus stop signals), several amino acids share codons. This redundancy helps protect against mutations and allows some wobble at the third base without changing the amino acid that gets added. It’s not nonredundant (which would mean a unique codon for each amino acid), not ambiguous (which would mean a codon codes for more than one amino acid), and not incomplete. Therefore, redundancy best describes the code.
