Verified step by step guidance

Understand that mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell.
Recall that human cells are diploid, meaning they have two sets of chromosomes, one from each parent. In humans, this is a total of 46 chromosomes.
During mitosis, the parent cell duplicates its chromosomes, resulting in 92 chromatids, but these are not separate chromosomes. They are pairs of sister chromatids.
The cell then divides, and each daughter cell receives one set of 46 chromosomes, identical to the original parent cell.
Therefore, after mitosis, each human cell ends up with 46 chromosomes, maintaining the diploid number.
