AQA A Level Biology: Meiosis Quiz

What is the primary result of meiosis in terms of genetic diversity?

• Daughter cells that are genetically identical to the parent cell

• Daughter cells that are genetically identical to each other

• No change in genetic material

• Daughter cells that are genetically different from each other

What process during meiosis contributes to genetic diversity by exchanging alleles?

• Mitosis

• Duplication

• Crossing over

• Binary fission

During which phase of meiosis does crossing over occur?

• Telophase

• Interphase

• Anaphase

• Prophase

What is independent assortment in meiosis?

• Chromosomes duplicating themselves

• Chromosomes moving to opposite poles

• Chromosomes aligning randomly at the metaphase plate

• Nucleus division into two nuclei

How many daughter cells are typically produced by meiosis?

• Four

• Two

• Eight

• One

Which of the following is a key difference between meiosis and mitosis?

• Mitosis results in haploid cells

• Mitosis does not involve cell division

• Meiosis results in diploid cells

• Meiosis results in haploid cells

What is the role of homologous chromosomes in meiosis?

• They prevent genetic diversity

• They duplicate to form sister chromatids

• They pair up and may exchange genetic material

• They remain unpaired throughout the process

Which event in meiosis increases the variation in genetic material?

• Cell membrane dissolution

• Crossing over and independent assortment

• Nuclear division

• DNA replication

What is the significance of meiosis in sexual reproduction?

• It eliminates chromosomes

• It creates identical genetic copies

• It doubles the chromosome number

• It reduces the chromosome number by half

Which stage of meiosis involves the separation of sister chromatids?

• Telophase I

• Prophase I

• Metaphase I

• Anaphase II
