Total number of meiotic division required for forming 100 zygotes/100 grains of wheat is Correct Answer 125

The total number of meiotic divisions required for forming 100 zygotes/100 grains of wheat is 125.
A zygote is formed by the combination of male and female gametes, which that means for 100 zygotes, 100 male and female gametes will be required.
Male gametes are formed by the process of microsporogenesis, and in this, 1 cycle leads to the formation of 4 pollen grains.
For 100 microspores, $$\frac{{100}}{4}$$ = 25 cycles of meiosis will be done.
Now, female gametes are formed by the process of megasporogenesis, and for each active megaspore, 1 cycle of meiotic division is required. Thus, for 100 megaspores, 100 cycles of meiosis will be done.
That is ultimate, 100 + 25 = 125 meiotic division will produce 100 grains or zygotes.
