Detailed explanation-1: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.
Detailed explanation-3: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.
Detailed explanation-4: -Both the daughter cells after the telophase stage will have the same number of chromosomes. When there are 46 chromosomes at the initial stage of mitosis, then daughter cells will have 46 chromosomes.
Detailed explanation-5: -When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing. Mitosis and meiosis, the two types of cell division.
