Multiple Choice
In mitosis, how does the number of chromosomes in each daughter cell compare to the original parent cell (assuming no errors in chromosome segregation)?
A
Each daughter cell has twice the number of chromosomes as the parent cell.
B
Each daughter cell has half the number of chromosomes as the parent cell.
C
Each daughter cell has the same number of chromosomes as the parent cell.
D
Each daughter cell has a random number of chromosomes due to independent assortment.
Verified step by step guidance1
Recall that mitosis is a type of cell division that results in two daughter cells each genetically identical to the parent cell.
Understand that during mitosis, the chromosomes are duplicated during the S phase of interphase, so the parent cell temporarily has twice the number of chromatids, but the chromosome number is defined by the number of centromeres.
During mitosis, sister chromatids are separated into two new nuclei, ensuring each daughter cell receives one copy of each chromosome.
Therefore, the chromosome number in each daughter cell after mitosis is the same as the original parent cell, maintaining genetic consistency.
This differs from meiosis, where chromosome number is halved, and independent assortment can cause variation, but mitosis preserves chromosome number exactly.
