Explanation: 

Detailed explanation-1: -Mutations that an individual inherits from their parents are called hereditary mutations. They are present in all body cells and can be passed down to new generations. Acquired mutations occur during an individual’s life.

Detailed explanation-2: -Phenotypic mutations are errors that occur during protein synthesis. These errors lead to amino acid substitutions that give rise to abnormal proteins.

Detailed explanation-3: -In biology, insertions or deletions of nucleotides in the coding region resulting in an altered sequence of amino acids at the translation of the codons are known as frameshift mutations. This type of mutation may result in phenotypic changes, for instance, the production of an altered protein.
