Detailed explanation-1: -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.

Detailed explanation-2: -Finally, during telophase II, the chromosomes are enclosed in nuclear membranes. Cytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-3: -Meiosis II is sometimes referred to as an equational division because it does not reduce chromosome number in the daughter cells-rather, the daughter cells that result from meiosis II have the same number of chromosomes as the “parent” cells that enter meiosis II.

Detailed explanation-4: -Telophase II: During telophase II, cell division begins again in each of the two daughter cells, creating 4 daughter cells. Each of these 4 daughter cells contains 23 chromosomes, making them haploid, and none of the 4 is exactly alike (due to crossing over and independent assortment).

Detailed explanation-5: –Humans have 46 chromosomes and there are 23 chromosomes in the telophase-II stage. Note: Telophase-II is the stage at which the group of chromosomes at each pole of the spindle gets enclosed by a nuclear envelope.
