One difference between mitosis and meiosis is ______.
A
both mitosis and meiosis result in diploid cells.
B
mitosis involves two rounds of cell division, while meiosis involves only one.
C
crossing over occurs during mitosis but not during meiosis.
D
mitosis produces two genetically identical daughter cells, while meiosis produces four genetically unique daughter cells.
Verified step by step guidance

Understand the key difference between mitosis and meiosis: Mitosis is a process of cell division that results in two genetically identical diploid daughter cells, while meiosis is a process that results in four genetically unique haploid daughter cells.
Recall that mitosis involves a single round of cell division, whereas meiosis involves two rounds of cell division (Meiosis I and Meiosis II).
Note that crossing over, which is the exchange of genetic material between homologous chromosomes, occurs during Prophase I of meiosis but does not occur during mitosis.
Eliminate the incorrect options: (1) Both mitosis and meiosis do not result in diploid cells, as meiosis produces haploid cells. (2) Mitosis involves only one round of cell division, not two. (3) Crossing over does not occur during mitosis.
Conclude that the correct answer is: 'Mitosis produces two genetically identical daughter cells, while meiosis produces four genetically unique daughter cells.' This highlights the fundamental difference in the outcomes of these two processes.
