Questions and Answers
What is the primary difference between meiosis and mitosis?
What is the primary difference between meiosis and mitosis?
- Mitosis leads to genetic variation, while meiosis produces genetically identical cells.
- Meiosis involves two rounds of cell division, while mitosis only has one round. (correct)
- Mitosis results in the formation of haploid cells, while meiosis forms diploid cells.
- Meiosis occurs only in reproductive organs, while mitosis occurs in all body cells.
During which stage of meiosis does crossing over occur?
During which stage of meiosis does crossing over occur?
- Metaphase I
- Prophase I (correct)
- Telophase I
- Anaphase I
What is the significance of independent assortment in meiosis?
What is the significance of independent assortment in meiosis?
- It promotes the formation of diploid zygotes during fertilization.
- It prevents the formation of gametes in reproductive organs.
- It leads to the random alignment of paternal and maternal chromosomes during metaphase I. (correct)
- It ensures that homologous pairs stick together during cell division.
