Verified step by step guidance1
Understand that a diploid organism has two sets of chromosomes, one from each parent. In this problem, the diploid number (2n) is given as 8 chromosomes.
Recall that mitosis is a type of cell division that results in two daughter cells, each genetically identical to the parent cell, maintaining the same chromosome number.
Since the parent cell is diploid with 8 chromosomes, after mitosis, each daughter cell should also have the same diploid number of chromosomes.
Therefore, the number of chromosomes in each daughter cell after mitosis is equal to the diploid number, which is 8 in this case.
Summarize that mitosis preserves the chromosome number, so the daughter cells have 8 chromosomes each, matching the original diploid number.
