Meiosis occurs in diploid cells. The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the chromosome number of the parental cell. Meiosis occurs only in sexually reproducing organisms.
Genetic recombination happens in meiosis 1, specifically in prophase 1, when crossing over happens between the two inner chromatids of a synapsed pair of homologous chromosomes. 3. Replication of DNA happens BEFORE meiosis begins, so it doesn't happen in either meiosis 1 or meiosis 2. It happens during interphase.
