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.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
