Why does reduction of chromosomes takes place in meiosis 1

WebTo achieve the reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. Because there are two rounds of division, the stages are designated with a “I” or “II.” Thus, meiosis I is the first round of meiotic division. Meiosis I reduces the number of chromosome sets from ... WebAnswer (1 of 5): Chromosome reduction from diploid (2n) to haploid (n) occurs in meiosis I. 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. sharper image shiatsu neck massager
