Total number of meiotic division required for forming 100 zygotes/100 grains of wheat is

1. 100
2. 75
3. 125
4. 50

Correct answer: 125

Solution

In flowering plants, one zygote requires one egg and one male gamete, each ultimately produced through meiosis. For 100 zygotes, the total meiotic divisions add up to 125 because the female side contributes 100 meioses and the male side contributes 25 meioses in wheat grain formation context.
