Answer 1

$\huge\star\:\:{\orange{\underline{\pink{\mathbf{Answer}}}}}$

The number of meiotic division required to produce 1000 pollen grains of wheat are 250.

》In meiotic division four daughter cells are produced.

》Each of these four daughter cells contain half the number of chromosomes.

❤ Therefore 1000 divided by 4

=250.

Answer 2

Answer:

250

Explanation:

For formation of 100 zygotes, 100 male gametes and 100 female gametes (eggs) are required. 100 male gametes are developed from 100 microspores (from 25 meiotic divisions) and 100 eggs are developed from 100 megaspores (from 100 meiotic division). Hence, number of meiotic divisions necessary for 100 zygotes formation = 25 + 100 = 125.
