Meiosis is a biological process in eukaryotes that reduces the number of chromosomes in a cell by half and introduces genetic variation. It produces four genetically unique haploid cells from each diploid parent cell, which are essential for sexual reproduction.
The main functions of meiosis are to reduce the number of chromosomes in the parent cell by half and to produce four genetically unique haploid cells from each diploid parent cell. In eukaryotes, this process is necessary for sexual reproduction. Meiosis begins with the duplication of each chromosome during the interphase. This is followed by two rounds of nuclear division where homologous chromosomes and then sister chromatids are separated into different nuclei. This process introduces genetic variation through crossover in prophase I and random alignment of chromosomes at metaphase I.
Diploid cells are those that contain two sets of chromosomes (one set from each parent). In contrast, haploid cells produced by meiosis contain only a single set of chromosomes. After meiosis, these haploid cells (sperm and eggs in animals) can fuse during fertilization to produce a diploid offspring with two sets of chromosomes. The genetic variation introduced during meiosis and fertilization is critical for the survival and evolution of species.
