DIFFERENTIATED CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a body cell divides through the process of mitosis, the chromosomes in the daughter cells
A
represent only half of the chromosomes in the parent cell.
B
are formed when chromosomes from the parent cell cross over.
C
represent only the healthiest chromosomes from the parent cell.
D
are identical to the chromosomes of the parent cell.
Explanation: 

Detailed explanation-1: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. Your body contains trillions of cells (thousands of millions).

Detailed explanation-2: -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-3: -There are now two cells, and each cell contains half the number of chromosomes as the parent cell. In addition, the two daughter cells are not genetically identical to each other because of the recombination that occurred during prophase I (Figure 4).
