Question

Match the LIST-I with LIST-II \[ \begin{array}{|l|l|} \hline \textbf{LIST I (Monosomics developed)} & \textbf{LIST II (Researchers)} \\ \hline A. \ \text{Oat} & I. \ \text{Clausen and co-workers} \\ B. \ \text{Wheat} & II. \ \text{Rajhathy and co-workers} \\ C. \ \text{Tobacco} & III. \ \text{Sears and co-workers} \\ D. \ \text{Cotton} & IV. \ \text{Endrizzi and associates} \\ \hline \end{array} \]

• A. A - I, B - II, C - III, D - IV
• B. A - II, B - I, C - III, D - IV
• C. A - II, B - III, C - I, D - IV
• D. A - III, B - IV, C - I, D - II

Hint:

Monosomics are useful in chromosome mapping and identifying linkage groups in crops.

Answer 1

The Correct Option is A

Step 1: Recall monosomics concept.
A monosomic is a genetic condition in which an organism has one chromosome less than the diploid number (2n-1). Researchers have developed monosomics in various crops for cytogenetic studies.
Step 2: Matching.
- Oat monosomics → Developed by Clausen and co-workers.
- Wheat monosomics → Developed by Rajhathy and co-workers.
- Tobacco monosomics → Developed by Sears and co-workers.
- Cotton monosomics → Developed by Endrizzi and associates.
Step 3: Conclusion.
Hence, the correct match is A - I, B - II, C - III, D - IV.
