If the process shown is meiosis, we would expect cells A, B, C, and D to have how many chromosomes
9966 [12]

Daughter cells in meiosis usually have half the number of chromosomes of their parents.

<h3>Chromosome number in meiosis</h3>

Meiosis is called reductional division for a reason. It is because the number of chromosomes of the parent cell is usually halved in the daughter cells.

For example, if a cell with 46 chromosomes undergoes meiosis to produce four daughter cells. Each of the daughter cells will have 23 chromosomes.

This is unlike mitosis in which daughter cells have the same number of chromosomes as their parents.
