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.
The purpose of meiosis is to reduce the normal diploid cells (2 copies of each chromosome / cell) to haploid cells, called gametes (1 copy of each chromosome per cell). In humans, these special haploid cells resulting from meiosis are eggs (female) or sperm (male). In yeast cells, they are spores.To carry out this specialized process, the cells duplicate their DNA but follow this by two rounds of division, instead of one.n humans, these special haploid cells resulting from meiosis are eggs (female) or sperm (male).
