1. **Understanding the Question**: The question asks for the term that describes the degree to which offspring (progeny) differ from their parents.

2. **Analyzing the Options**:
- **Inheritance**: This term refers to the process by which genetic traits are passed from parents to their offspring. However, it does not specifically describe the degree of difference.
- **Heredity**: This term is similar to inheritance and refers to the passing of traits from parents to offspring. It also does not capture the concept of difference.
- **Genetics**: This is the branch of biology that studies genes, genetic variation, and heredity. It encompasses all aspects of heredity but does not specifically refer to the degree of difference.
- **Variation**: This term refers to the differences in traits among individuals, which can result from genetic differences. It specifically addresses the degree of difference between progeny and their parents.

3. **Identifying the Correct Answer**: Upon analyzing the definitions, the term that best describes the degree by which progeny differ from their parents is **Variation**.

4. **Conclusion**: The correct answer to the question is **Variation**.
