In meiosis, a single diploid cell undergoes two rounds of division, resulting in four haploid cells. Each of these new cells contains half the number of chromosomes of the original cell. For example, if the original cell has 46 chromosomes (as in humans), each of the four new cells will have 23 chromosomes.
4 cells
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
The daughter cells of meiosis I contain the haploid number of chromosomes, which is half the number of chromosomes found in the parent cell. In humans, each daughter cell of meiosis I contains 23 chromosomes.
cells and genetics
After meiosis II, human sex cells (gametes) have 23 chromosomes. This is half the number of chromosomes found in somatic cells, which have 46 chromosomes. Meiosis reduces the chromosome number by half to ensure that when fertilization occurs, the resulting zygote will have the correct diploid number of 46 chromosomes.

Meiosis starts with one cell that has a diploid number of chromosomes, which means it has two sets of chromosomes.
