1. Which process produces gametes in humans?
A. Mitosis
B. Meiosis
C. Binary fission
D. Budding
Correct Answer: B
Rationale: Meiosis reduces the chromosome number by half to
produce gametes.
2. How many rounds of division occur in meiosis?
A. One
B. Two
C. Three
D. Four
Correct Answer: B
Rationale: Meiosis has two successive divisions: meiosis I and II.
,3. In which phase do homologous chromosomes separate?
A. Prophase I
B. Metaphase I
C. Anaphase I
D. Telophase I
Correct Answer: C
Rationale: Homologous chromosomes are pulled to opposite poles
in Anaphase I.
4. In which phase do sister chromatids separate?
A. Anaphase I
B. Anaphase II
C. Metaphase I
D. Telophase II
Correct Answer: B
Rationale: Sister chromatids separate during Anaphase II.
5. What is the ploidy of gametes?
A. Diploid
B. Haploid
C. Triploid
D. Tetraploid
Correct Answer: B
Rationale: Gametes contain one set of chromosomes (haploid).
,6. Which process increases genetic variation during meiosis?
A. DNA replication
B. Crossing over
C. Cytokinesis
D. Mitosis
Correct Answer: B
Rationale: Crossing over during prophase I exchanges genetic
material between homologs.
7. Which phase of meiosis aligns chromosomes at the center?
A. Metaphase I
B. Metaphase II
C. Prophase I
D. Telophase II
Correct Answer: A
Rationale: Homologous chromosomes line up at the metaphase
plate during Metaphase I.
8. Which phase of meiosis aligns sister chromatids at the center?
A. Metaphase I
B. Metaphase II
C. Prophase II
D. Telophase II
Correct Answer: B
, Rationale: Metaphase II aligns sister chromatids at the metaphase
plate.
9. What is independent assortment?
A. Separation of sister chromatids
B. Random orientation of homologs
C. Crossing over
D. DNA replication
Correct Answer: B
Rationale: Independent assortment during metaphase I creates
genetic variation.
10. Which type of RNA carries amino acids to ribosomes?
A. mRNA
B. tRNA
C. rRNA
D. snRNA
Correct Answer: B
Rationale: tRNA delivers specific amino acids for protein synthesis.
11. Which type of RNA forms the ribosome?
A. mRNA
B. tRNA
C. rRNA
D. snRNA
