WebChromosome number. Different species have different numbers of chromosomes. For example, humans are diploid (2n) and have 46 chromosomes in their normal body cells. … 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.
