Multiple Choice
In a typical human somatic cell, mitosis produces two daughter cells. How many chromosomes does each daughter cell have after mitosis (assuming no errors)?
A
The chromosome number is reduced by half compared to the parent cell
B
23 chromosomes
C
46 chromosomes
D
92 chromosomes
Verified step by step guidance1
Recall that a typical human somatic cell is diploid, meaning it contains 46 chromosomes arranged in 23 pairs.
Understand that mitosis is a process of cell division that results in two daughter cells genetically identical to the parent cell.
During mitosis, the chromosomes are duplicated during the S phase of the cell cycle, so the cell temporarily has 92 chromatids (46 chromosomes each consisting of two sister chromatids).
However, mitosis separates the sister chromatids into two nuclei, so each daughter cell receives one copy of each chromosome.
Therefore, each daughter cell ends up with the same diploid number of chromosomes as the original parent cell, which is 46 chromosomes.
