Which of the following variations are temporary and have nothing to do with the last or next generation

Options

A. Heredity variation
B. Environmental variations
C. Discontinuous variations
D. Continuous variations

Answer

To solve the question regarding which variations are temporary and have no relation to the last or next generation, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Types of Variations**:
- Variations can be classified into different categories based on their origin and inheritance.

2. **Evaluate Heredity Variations**:
- **Definition**: These are variations that are passed from parents to offspring through genes.
- **Analysis**: Since heredity variations are inherited, they can be observed in subsequent generations.
- **Conclusion**: This option is incorrect.

3. **Evaluate Environmental Variations**:
- **Definition**: These variations occur due to changes in the environment and are not influenced by genetic inheritance.
- **Analysis**: Environmental variations are temporary and do not get passed on to the next generation. They are a response to external conditions.
- **Conclusion**: This option is correct.

4. **Evaluate Discontinuous Variations**:
- **Definition**: These are variations that appear suddenly and can be distinct, often due to genetic mutations.
- **Analysis**: Discontinuous variations can also be inherited, meaning they can appear in future generations.
- **Conclusion**: This option is incorrect.

5. **Evaluate Continuous Variations**:
- **Definition**: These variations occur gradually and show a range of phenotypes (e.g., height, skin color).
- **Analysis**: Continuous variations can also be inherited, as they are influenced by multiple genes.
- **Conclusion**: This option is incorrect.

### Final Answer:
The correct answer is **environmental variations**, as they are temporary and do not affect the inheritance of traits in future generations.
