Vedclass · Answer

(A) Pollen mother cells $(PMC)$ are diploid $(2n)$ cells that undergo meiosis to produce microspores or pollen grains.Meiosis is a reductional division,which reduces the chromosome number to half $(n)$.If the $PMC$ has $42$ chromosomes $(2n = 42)$,then the pollen grains,being haploid,will have $n = 42/2 = 21$ chromosomes.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion: If pollen mother cells have $42$ chromosomes,the pollen has only $21$ chromosomes.
Reason: Pollens are formed after meiosis in pollen mother cells.
