Meiosis Quiz

What is the main purpose of meiosis?

• To produce identical daughter cells
• To reduce the number of chromosomes by half
• To increase genetic diversity
• To repair damaged DNA

Which of the following best describes homologous chromosomes?

• Chromosomes with different lengths
• Chromosomes from different species
• Chromosomes with the same genes, length, and centromere position
• Chromosomes that don't pair up during meiosis

What is the difference between a haploid and diploid cell?

• Haploid cells have twice as many chromosomes as diploid cells
• Diploid cells have twice as many chromosomes as haploid cells
• Haploid cells and diploid cells have the same number of chromosomes
• Haploid cells have no chromosomes

During which phase of meiosis does crossing over occur?

• Metaphase I
• Anaphase I
• Prophase I
• Telophase I

What is the significance of crossing over in meiosis?

• It reduces the number of chromosomes
• It increases genetic variability
• It creates identical daughter cells
• It speeds up the process of meiosis

In which phase of meiosis I do homologous chromosomes align at the cell's equator?

• Prophase I
• Metaphase I
• Anaphase I
• Telophase I

What is unique about how spindle fibers attach to chromosomes in Metaphase I?

• They don't attach at all
• They attach to both sides of each chromosome
• They attach to only one side of each chromosome
• They attach randomly

What happens during Anaphase I of meiosis?

• Sister chromatids separate
• Homologous chromosomes separate
• Cell membrane forms
• DNA replicates

After Telophase I and cytokinesis, how many cells are formed?

• 1
• 2
• 3
• 4

What is the ploidy of the cells after Meiosis I?

• Haploid
• Diploid
• Triploid
• Tetraploid
