In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. Prophase I. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Mitosis and meiosis. Normal cell division in all cells, except germ cells, occurs by 2 mechanical processes that initially divide the nucleus then the cell cytoplasm. This process produces two (daughter) cells that should be genetically identical to the parent cell. Germ cells, oocyte and spermatozoa, undergo meiotic cell division. 1  Mitosis segregation of chromosomes and formation of 2 nuclei.  Cytokinesis splitting of the cell as a whole into 2 daughter cells.
