Question:
How many times the diploid number of chromosomes of Ophioglossum is more than haploid number of chromosomes of Zea mays?
How many times the diploid number of chromosomes of Ophioglossum is more than haploid number of chromosomes of Zea mays?
Show Hint
Ophioglossum has the highest known chromosome number in plants.
Always divide diploid by haploid for comparison.
Check units carefully: diploid vs haploid numbers.

The Correct Option is A
Solution and Explanation
Ophioglossum has a diploid chromosome number of 1260. Zea mays has a haploid number of 20. The ratio of Ophioglossum diploid to Zea mays haploid is \(1260/20 = 63\). Hence, the diploid number of Ophioglossum is 63 times that of haploid Zea mays.
