The chromosomes are first replicated during interphase. In meiosis I, the homologous chromosomes first pair (synapse) with one another. During synapses, pieces of the chromatids can be exchanged between the homologues. The homologous chromosomes are separated by the end of meiosis I.
In meiosis II, the chromatids are separated from each other, four haploid daughter cells each with single stranded chromosomes are formed.
If it is a male, four sperm are formed. In females, one egg and four polar bodies are formed.
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.
The two meiotic divisions are called meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing-over before separating, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in four daughter cells, each with a unique combination of genes.
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.

No, meiosis does not result in the doubling of chromosomes. Instead, it reduces the number of chromosomes in a cell by half.
The chromosomes divide.
the synapsis and crossing over of homologous chromosomes
They mate.
The chromosome number at the end of meiosis is half of the parent cell
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
They must double
Chromosomes move to opposite poles of the cell.
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.

Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
