Number of chromosomes in wheat
WebThe number of chromosomes becomes haploid in meiosis I, because the actual sister chromatids are not pulled apart by spindle fibers. For example, if a cell was undergoing meiosis, and had a total of 4 chromosomes in it, then 2 of them would go to one daughter cell, and 2 of them would go to the other daughter cell. That makes 2 haploid cells. Web22 jan. 2024 · Humans have 23 sets of homologous chromosomes for a total of 46 chromosomes.
