How many chromosomes are in mitosis?

Published in Cell Division 2 mins read

A cell undergoing mitosis results in two daughter cells, each containing a total of 46 chromosomes.

During mitosis, a single cell divides into two identical daughter cells. Here’s a breakdown:

  • Before mitosis begins, the cell's chromosomes are duplicated, resulting in two identical copies of each chromosome.
  • During mitosis, these identical copies are pulled apart and distributed evenly to each of the two new cells.
  • As a result, each newly formed daughter cell receives a complete and identical set of 46 chromosomes, just like the original parent cell.


Phase of Mitosis Chromosome Status Chromosome Count
Before Mitosis Duplicated 92
During Separation Separating into sister chromatids 92
After Mitosis Single copies in each cell 46 (per cell)


This process ensures that each new cell has the same genetic information as the original cell. According to the provided reference, "When the cell divides, the copies are pulled apart, and each new cell gets one identical copy of each chromosome. This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes."
