D
n chromosomes
Verified step by step guidance1
Understand that mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell.
Recall that the parent cell starts with a diploid number of chromosomes, which is represented as 2n, where 'n' is the number of unique chromosomes.
During mitosis, the chromosomes are duplicated during the S phase of the cell cycle, but the number of chromosomes remains the same as the original parent cell.
The duplicated chromosomes are then equally divided between the two daughter cells during the mitotic phase, ensuring each daughter cell receives an identical set of chromosomes.
Conclude that each daughter cell will contain the same number of chromosomes as the parent cell, which is 2n chromosomes.
