Given below are two statements, one is labelled as Assertion (A) and the other one is labelled as Reason (R).
Assertion (A): Meiotic division of one somatic (2n) cell gives rise to four haploid (n) daughter cells.
Reason (R): The reduction in chromosome number of daughter cells is mainly due to a single S phase during the premeiotic interphase followed by two successive nuclear divisions.
