Meiosis is necessary in order for sexual reproduction to occur. It ensures that when the gametes (eg. sperm and egg) combine, the new organism has the correct number of chromosomes.
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).
