Explanation: 

Detailed explanation-1: -As previously mentioned, the first round of nuclear division that occurs during the formation of gametes is called meiosis I . It is also known as the reduction division because it results in cells that have half the number of chromosomes as the parent cell.

Detailed explanation-2: -Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.

Detailed explanation-3: -Anaphase I of meiosis is characterized by separation of homologous chromosomes. This leads to reduction in chromosome number to half of that present in the mother cell.
