Haploidy: During reduction division in meiosis, diploid (2n) becomes haploid (n). 2) If the homologous chromosomes do not separate in meiosis I, then one daughter cell from this division will have four copies of this chromosome and the other cell will have none. In meiosis II, sister chromatids will separate; leaving two gametes with two copies of the chromosome and two gametes with no copies of the chromosome. 3) As cells divide mitotically, each chromosome consists of identical sister chromatids that are separated to form genetically identical daughter cells. Although the second division of meiosis appears to be a similar process, the ‘sister’ chromatids are
