Detailed explanation-1: -The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half-from 46 to 23-to form sperm and egg cells.
Detailed explanation-2: -The number of chromosomes in human cells are 46. i.e, these are present in pairs of 23. These pairs break apart and get separated in meiosis I. Thus, each of the two daughter cells formed after first meiotic division have half the number of chromosomes, i.e., 23.
Detailed explanation-3: -Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells. Unicellular eukaryotes, such as yeasts, can undergo meiosis as well as reproducing by mitosis.
Detailed explanation-4: -Meiosis, from the Greek word meioun, meaning “to make small, ” refers to the specialized process by which germ cells divide to produce gametes. Because the chromosome number of a species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis.
