Gene mutations can be categorized into which two main types?

• A. Phenotypic and genotypic mutations
• B. Hereditary mutations and acquired mutations
• C. Silent and missense mutations
• D. Point mutations and frameshift mutations

Answer: (B)

Gene mutations can indeed be broadly categorized into hereditary mutations and acquired mutations. Hereditary mutations are those that can be passed from one generation to the next, typically occurring in the germ cells (sperm and egg) and present in every cell of an offspring. These mutations can lead to inherited disorders and contribute to the genetic diversity within a population. Acquired mutations, on the other hand, occur in somatic cells and are not passed on to offspring. These mutations can arise from various environmental factors or errors during DNA replication and may lead to conditions such as cancer, but they do not affect the germline and therefore are not inherited. The other choices represent more specific categorizations or types of mutations rather than the broad categories. For instance, silent and missense mutations refer to specific outcomes of point mutations at the level of protein synthesis, while point mutations and frameshift mutations are specific types of mutations based on their effect on the DNA sequence. Thus, the classification into hereditary and acquired mutations provides a more foundational understanding of how mutations can affect organisms across generations.
