Find a disadvantage of hybrid seeds

Options

A. More yield
B. More genetic recombinations
C. More vigour and growth
D. Have to be produced every year

Answer

**Step-by-Step Solution:**

1. **Understanding Hybrid Seeds**: Hybrid seeds are produced by cross-breeding two different plant varieties that possess desirable traits. This process aims to combine the best characteristics of both parent plants.

2. **Advantages of Hybrid Seeds**: Hybrid seeds are known for their high yield potential, improved vigor, and better growth rates. They can also exhibit a variety of desirable traits such as disease resistance and adaptability to different environmental conditions.

3. **Disadvantage of Hybrid Seeds**: One significant disadvantage of hybrid seeds is that they are often sterile. This means that the seeds produced from hybrid plants may not be viable for planting, which forces farmers to purchase new hybrid seeds every planting season.

4. **Economic Implications**: Since hybrid seeds need to be bought every year, this can lead to increased costs for farmers. The necessity to continually purchase new seeds can make hybrid farming economically burdensome, especially for small-scale farmers.

5. **Conclusion**: Therefore, the main disadvantage of hybrid seeds is that they must be produced and purchased every year due to their sterility, which can be expensive for farmers.

**Final Answer**: The disadvantage of hybrid seeds is that they have to be produced every year, which incurs additional costs.
