Multiple Choice
In mitosis, if a diploid human somatic cell (2n = 46) divides, how many chromosomes does each daughter cell have at the end of mitosis (after cytokinesis)?
A
23 chromosomes
B
46 chromosomes
C
92 chromosomes
D
The chromosome number is randomly halved or doubled
Verified step by step guidance1
Recall that a diploid human somatic cell has 2n = 46 chromosomes, where '2n' indicates two sets of chromosomes, one from each parent.
Understand that mitosis is a process of cell division that results in two daughter cells genetically identical to the original cell, maintaining the same chromosome number.
During mitosis, the chromosomes are duplicated during the S phase of the cell cycle, but the chromosome number itself does not change; sister chromatids separate to opposite poles.
After mitosis and cytokinesis, each daughter cell receives one complete set of chromosomes, which means the chromosome number remains the same as the original diploid cell.
Therefore, each daughter cell will have 46 chromosomes, the same as the parent cell, because mitosis preserves the chromosome number.
