Cell Structure and Function

In which phase of meiosis does synapsis occur?

• Prophase II
• Metaphase I
• Telophase II
• Prophase I

What is the outcome of telophase II in meiosis?

• Formation of two diploid nuclei
• Formation of four diploid nuclei
• Formation of two haploid nuclei
• Formation of four haploid nuclei

What happens to chromosomes during anaphase II of meiosis?

• Homologous chromosomes pair up
• Crossing over occurs between homologous chromosomes
• Sister chromatids separate and move to opposite poles
• Chromosomes condense and become visible

What is the main significance of meiosis in sexually reproducing organisms?

• Increases chromosome number in gametes
• Maintains a constant chromosome number across generations
• Produces identical daughter cells
• Promotes rapid tissue growth

What occurs to the centromeres during anaphase-I of meiosis?

• They divide into two
