Whereas the number of chromosomes is reduced to half in first reduction division of meiosis, then what is the need for second mitotic division

For the segregation of replicated chromosomes

For equal distribution of haploid chromosomes

For the formation of four gametes

For equal distribution of genes on chromosomes

Solution

(a) The reduction of $DNA$ content does not occur in meiosis-$I$. Truely haploid nuclei in terms of $DNA$ contents as well as chromosomes number are formed in meiosis-$II$.

When the chromatids of each chromosome are separated in to different nuclei. Thus meiosis-$II$ is necessary.
