The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about mutations that are fatal to organisms. This indicates that we are looking for a specific type of mutation that leads to death or severe impairment of an organism. 2. **Identifying the Type of Mutation**: The term used to describe mutations that are fatal is "lethal mutation." These mutations can lead to the death of the organism either directly or by causing severe health issues. 3. **Characteristics of Lethal Mutations**: Lethal mutations are often associated with specific genes known as lethal genes. These genes can be recessive, meaning that they only express their lethal effects when present in a homozygous state (when an organism has two copies of the lethal allele). 4. **Examples of Lethal Mutations**: Some well-known examples of diseases caused by lethal mutations include: - **Sickle Cell Anemia**: A genetic disorder that affects hemoglobin in red blood cells, leading to various complications and can be fatal. - **Cystic Fibrosis**: A genetic disorder that affects the respiratory and digestive systems, which can also lead to severe health issues and reduced life expectancy. 5. **Conclusion**: Therefore, the mutations that prove fatal for the organism are called "lethal mutations." **Final Answer**: Lethal mutations. ---
