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

Monosomic Concept: A monosomic condition is characterized by an organism possessing one less chromosome than its diploid number (2n-1). Monosomics have been engineered in multiple crop species for cytogenetic research.
Matching of Monosomics to Developers:
- Oat monosomics were developed by Clausen's team.
- Wheat monosomics were developed by Rajhathy's team.
- Tobacco monosomics were developed by Sears' team.
- Cotton monosomics were developed by Endrizzi's team.
Conclusion: The correct pairings are A - I, B - II, C - III, and D - IV.
