Both the environment and the genotype are important in the development of

Options

A. disease
B. country
C. plant quarantine
D. phenotype

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Genotype**: This refers to the genetic makeup of an organism, which includes all the genes it carries.
- **Phenotype**: This is the observable characteristics or traits of an organism, which can include physical appearance, behavior, and physiological properties.
- **Environment**: This encompasses all external factors that can influence the development and expression of traits in an organism.

2. **Relationship Between Genotype and Phenotype**:
- The genotype provides the potential for certain traits to be expressed, but the actual expression of these traits (the phenotype) can be influenced by environmental factors.
- For example, a plant may have the genetic potential to grow tall (genotype), but if it is not given enough sunlight or nutrients (environment), it may not reach its full height (phenotype).

3. **Conclusion**:
- Both genotype and environment play crucial roles in determining the phenotype of an organism. Therefore, the correct answer to the question is that both the environment and genotype are important in the development of the **phenotype**.

### Final Answer:
The correct answer is **phenotype**.
