The chromosomes divide.

the synapsis and crossing over of homologous chromosomes
They mate.
Meiosis starts with one cell that has a diploid number of chromosomes, which means it has two sets of chromosomes.
The chromosome number at the end of meiosis is half of the parent cell
They must double
Chromosomes move to opposite poles of the cell.
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.
During meiosis, the number of chromosomes is halved. This process results in the formation of sex cells (sperm and egg) with half the number of chromosomes as the parent cell.
Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
In meiosis, chromosomes replicate during interphase before the start of cell division. This process ensures that each daughter cell will receive the correct number of chromosomes.
