Question

Corn ($Zea$ $mays$) has diploid number of 20 chromosomes, the number of chromosomes of microspore mother cell is ........................

• A. 10
• B. 20
• C. 30
• D. 40

Answer 1

Answer: (B)

20

Corn has diploid number of chromosomes. It is thus given as 2n = 20. The megaspore mother cell is a diploid cell, 2n = 20. Megaspore mother cell later undergoes meiosis to form microspores and then the pollen grains which are haploid in nature.
