Explanation
## Step 1:First, let's understand the two processes: mitosis and meiosis. Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell. This means that these daughter cells contain the same number of chromosomes as the parent cell.## Step 2:On the other hand, meiosis is a process of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. These cells are used in sexual reproduction and are not genetically identical.## Step 3:Human body cells, except gametes, have 23 pairs of chromosomes. This means that they have a total of 46 chromosomes. When a cell divides by mitosis, the number of chromosomes remains the same. Therefore, each daughter cell will have 46 chromosomes.## Step 4:When a cell divides by meiosis, the number of chromosomes is halved. Therefore, each daughter cell will have 23 chromosomes.## Step 5:In terms of the number of daughter cells produced, mitosis results in two daughter cells, while meiosis results in four daughter cells.
