Detailed explanation-1: -The answer is 22. If the chromosome number for an organism is 22 before mitosis, then the chromosome number of each daughter cell after mitosis has taken place will also be 22.
Detailed explanation-2: -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.
Detailed explanation-3: -When the cell divides, the copies are pulled apart, and each new cell gets one identical copy of each chromosome. This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes. Beginning soon after fertilization (see below), all of the cells in your body were made this way.
Detailed explanation-4: -Thus, the parent cell with 24 chromosomes after undergoing mitosis will form two daughter cells each with 24 chromosomes.
