Which of the following species has the chromosome complement similar to that of Triticum aestivum?

Options

A. Zea mays
B. Secale cereale
C. Gossypium
D. Aegilops

Explanation

To determine which species has a chromosome complement similar to that of Triticum aestivum (common wheat), we need to analyze the chromosome numbers of the given options.

1. **Identify the chromosome number of Triticum aestivum**:
- Triticum aestivum has a diploid chromosome number of 2n = 42 (not 26 as mentioned in the video). This is an important correction.

2. **Examine the options**:
- **Zea mays (corn)**: The chromosome number is 2n = 20. This does not match.
- **Secale cereale (rye)**: The chromosome number is 2n = 14. This does not match.
- **Gossypium (cotton)**: The chromosome number is 2n = 26. This does not match.
- **Aegilops**: This is a genus of grass, and the chromosome number can vary, but it is generally around 2n = 14. This does not match.

3. **Conclusion**:
- None of the options provided have the same chromosome number as Triticum aestivum. However, if we consider Gossypium (cotton), it has a similar number of chromosomes (though not identical), but it is not the correct answer based on the exact match of chromosome number.

**Final Answer**: None of the options have the same chromosome complement as Triticum aestivum.
