During mitosis, each new cell receives copies of all of the original chromosomes. This ensures that each new cell has the same genetic information as the original parent cell. Option A is incorrect as each new cell receives the same number of chromosomes as the original cell. Option C is incorrect as it only applies to the end result of meiosis, not mitosis. Option D is incorrect as sister chromatids are identical due to DNA replication, though there may be occasional mutations. Option E is incorrect as all chromosomes, including the sex chromosomes, are duplicated during mitosis.
