Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
Interphase occurs once for cells undergoing meiosis. During interphase, the cell duplicates its DNA and prepares for division. After interphase, meiosis involves two rounds of cell division (meiosis I and meiosis II), but interphase itself is not repeated between these divisions.
Reproduction This repeatidly dividing cell has undergone somatic cell divisions. Mitotic divisions add to new cells of the identical chromosome number and help in growth of an individual..
Meiosis produces four daughter cells. This is because there are two divisions in meiosis. The first division produces two cells. Each of these cells then divides, producing a total of four.

Meiosis consists of two separate divisions : meiosis 1 and meiosis 2Meiosis 1 : members of each homologous pair of chromosomes separate.Meiosis 2 : the two cromatids of each chromosome separate.
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II

Even if there was that kind of sex cell, I don't think it would survive! Sex cells ALWAYS have 46 chromosomes. At the end of meiosis, as long as there are no mistakes, each sperm or egg cell would have 23 chromosomes.
meiosis involves 2 cell divisions while mitosis involves 1
Interphase occurs once for cells undergoing meiosis. During interphase, the cell duplicates its DNA and prepares for division. After interphase, meiosis involves two rounds of cell division (meiosis I and meiosis II), but interphase itself is not repeated between these divisions.
During meiosis I, each nucleus will have half the number of chromosomes as the original parent cell. This is because meiosis I involves the separation of homologous chromosomes, resulting in two daughter cells with a haploid number of chromosomes.
Many celled organisms, or eukaryotes, have a bounded nucleus and can use the processes of mitosis and meiosis.
After meiosis in a cell that originally has 46 chromosomes, each resulting nucleus will have 23 chromosomes. This is due to the process of meiosis, which involves two rounds of cell division that result in the formation of four daughter cells, each with half the number of chromosomes as the original cell.
in meiosis, two new haploid sex cells are "born" by the division of two other haploid sex cells. So, at the end, there are 4 nuclei.
