DNA is not replicated during meiosis. Homologous chromosomes exchange DNA during meiosis but not during mitosis. Meiosis occurs only in haploid organisms. At the start of meiosis, each chromosome consists of 4 chromatids. Daughter nuclei are virtually genetically identical to each other.
Homologous chromosomes synapse.
At the start of meiosis I, each chromosome consists of two chromatids. I, the chromatids that make up a chromosome in meiosis II are not identical. Mitotic spindle, made of microtubules, forms. One chromatid of each chromosome gets pulled to each pole of the cell. A nuclear membrane forms around each set of chromosomes, resulting in two daughter nuclei.
