    3. Bone cells
  • INCORRECT! sperms can’t undergo cell divisions.
  • CORRECT!
  • INCORRECT! sperms can’t undergo cell divisions.

Question 4: Which of the following correctly describes independent assortment in meiosis?
    1. Exchange of genetic materials between sister chromatids.
    2. Rearrangement of chromosomes.
    3. Rearrangement of alleles along the chromosome.
  • INCORRECT! Exchange of genetic materials between sister chromatids occurs in crossing over.
  • CORRECT! Independent assortment refers to the random separation of homologous chromosomes during meiosis.
  • INCORRECT! Exchange of genetic materials between sister chromatids occurs in crossing over.
  • INCORRECT! Exchange of genetic materials between sister chromatids occurs in crossing over. Rearrangement of alleles along the chromosome occurs in mutation.
Question 5: Which of the following correctly states the difference between mitosis and meiosis?
    1. Replication of chromosomes occurs before mitosis but not meiosis.
    2. Pairing of homologous chromosome occurs in meiosis only.
    3. 2 haploid daughter cells form after each cycle of meiosis while 2 diploid daughter cells form after mitosis.
  • INCORRECT! Replication of chromosomes occurs before both mitosis and meiosis.
  • CORRECT!
  • INCORRECT! Replication of chromosomes occurs before both mitosis and meiosis.
  • INCORRECT! Replication of chromosomes occurs before both mitosis and meiosis; 4 haploid daughter cells form after each cycle of meiosis.
