The options given are incorrect. Correct answer is 250/500.

To produce one seed we require one egg and one sperm.

One functional megaspore or ovum is formed by one meiotic division of megaspore mother cell. Thus, to produce 200 eggs, 200 meiotic divisions would be required

Four functional microspores or sperms are formed from one meiotic division of microspore mother cell. Thus, to produce 200 sperms, only 50 meiotic divisions are required.

Hence, total 250 meiotic divisions are required to produce 200 seeds.

Similarly, 500 meiotic divisions are required to produce 400 seeds.

Give number of seed form ofter 50 meiosis
