Which of the following statements regarding the differences between mitosis and meiosis is FALSE?
A
Meiosis involves two rounds of cell division, whereas mitosis involves only one.
B
Homologous chromosomes separate during anaphase of mitosis, but not during meiosis.
C
Mitosis results in two genetically identical diploid cells, while meiosis produces four genetically unique haploid cells.
D
Crossing over occurs during meiosis but not during mitosis.
Verified step by step guidance
1
Step 1: Begin by understanding the key differences between mitosis and meiosis. Mitosis is a process of cell division that results in two genetically identical diploid cells, while meiosis produces four genetically unique haploid cells. This distinction is crucial for understanding the problem.
Step 2: Recall that meiosis involves two rounds of cell division (meiosis I and meiosis II), whereas mitosis involves only one round of cell division. This is another fundamental difference between the two processes.
Step 3: Analyze the statement about homologous chromosomes. In mitosis, homologous chromosomes do not pair or separate; instead, sister chromatids separate during anaphase. In meiosis, homologous chromosomes separate during anaphase I, and sister chromatids separate during anaphase II. This statement about homologous chromosomes separating during anaphase of mitosis is false.
Step 4: Consider the statement about crossing over. Crossing over occurs during prophase I of meiosis, where homologous chromosomes exchange genetic material, leading to genetic diversity. This does not occur during mitosis.
Step 5: Review all the statements provided in the problem and identify the false one based on the biological processes described above. The false statement is the one claiming that homologous chromosomes separate during anaphase of mitosis, as this does not happen in mitosis.
