The new cells produced by this division have the exactly same chromosomes as the parent cell. Reduction of the diploid chromosome set to the haploid set homologue recombination only takes place in germ cells of multicell eucaryotes production of sperms and eggs involves two nuclear divisions rather than one. Muerte celular biologia ciclo celular v2 egg educacion duration. Think think meiosis is the process in which one cell divides into four daughter cells that have half the number of chromosomes as the parent cell. Meiosis cell division definition, examples, diagrams. Mitotic cell division produces daughter cell identical to the parent. Cuadros comparativos sobre mitosis y meiosis cuadro comparativo.
