How many pollen mother cells will form 1000 pollen grains

How many pollen mother cells will form 1000 pollen grains Correct Answer 250

250 pollen mother cells will form 1000 pollen grains.
One diploid microspore mother cells by meiosis form 4 tetrads of haploid microspores which become 4 pollen grains.
Thus, 250 pollen mother cells will produce 1000 pollen grains, by undergoing 50 rounds of meiosis.

Consider the following statements regarding Xenia and choose the correct answer:
1. If a white variety (yy) is pollinated with pollen from a yellow variety (YY), one of the male gametes (Y) will unite with the egg (y) to produce a hybrid embryo (Yy) which will act as a heterozygote for yellow endosperm in the next generation
