What is a major difference between mitosis and meiosis I in a diploid organism?

Question

Quizplus · Accepted Answer

The major difference between mitosis and meiosis I in a diploid organism is that in mitosis, sister chromatids separate, while in meiosis I, homologous pairs of chromosomes separate. This results in the formation of genetically identical daughter cells in mitosis, whereas in meiosis I, daughter cells are genetically diverse due to the separation of homologous pairs of chromosomes. Option A correctly states this difference. Option B is incorrect because homologous pairs of chromosomes separate in meiosis I, not meiosis II. Option C is incorrect because DNA replication takes place before both mitosis and meiosis I. Option D is incorrect because meiosis I results in daughter cells that are genetically diverse, not identical.
