Chromosome number meiosis

Weband (3) the chromosome number is reduced to half after meiosis I, so that the daughter cells resulting from meiosis I are haploid (23 chromosomes) (Fig. 16.11). From: Clinical … WebMeiosis is a series of events that arrange and separate chromosomes into daughter cells. During the interphase of meiosis, each chromosome is duplicated. In meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four haploid daughter cells, each with half the number of chromosomes as the parent cell.
