WebThis reduction in chromosome number is accomplished by two sequential rounds of nuclear and cell division (called meiosisI and meiosis II), which follow a single round of DNAreplication. Like mitosis, meiosis I initiates after S phasehas been completed and the parental chromosomes have replicated to produce identical sister chromatids. WebAug 7, 2016 · Meiosis I is reduction division . Explanation: Meiosis takes place in diploid germ cells for the formation of haploid gametes. Thus the chromosome number must come down to half in each gamete. In meiosis I, homologous chromosomes of a single cell separate to achieve the desired result.
