Which type of mutation is least likely to affect the phenotype of a plant, as it does not change the amino acid sequence?

Paragraph for question 13 to 16 Mutations are alterations in the DNA sequence that can occur in various forms, such as point mutations, where a single base is changed, or deletions and insertions, which result in the loss or addition of DNA segments. Substitutions involve the replacement of bases, while inversions reverse a DNA segment. Frameshift mutations, caused by insertions or deletions, disrupt the reading frame of genes. When a mutation leads to the replacement of one amino acid with another in a plant protein, it is known as ”a” . Mutations play a significant role in plant breeding, as they can introduce beneficial traits, enhance b , and improve crop resistance to diseases or environmental stresses.
