Vedclass · Answer

(B) Assertion $A$ is true because meiosis is a specialized type of cell division that reduces the chromosome number by half,which is only possible in diploid $(2n)$ cells to produce haploid $(n)$ gametes.Reason $R$ is also true because during meiosis-$I$,the homologous chromosomes separate,resulting in the reduction of the chromosome number from diploid to haploid,hence it is called reductional division.However,the reason $R$ explains why meiosis is a reductional division,but it does not directly explain why meiosis is restricted to diploid cells. Therefore,$R$ is not the correct explanation of $A$.

$A$: Meiosis occurs only in diploid $(2n)$ cells.
$R$: Meiosis-$I$ is known as reductional division.
