Understanding Meiosis: Key Concepts

What stage of Meiosis is being shown and described:

The homologs of each chromosome pair separate and are pulled to opposite ends

• Prophase 1

• Metaphase 1

• Anaphase 1

• Telophase 1

Which of the following is the correct order of stages in meiosis I?

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

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

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

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

What is the main difference between meiosis and mitosis?

• Meiosis results in two identical daughter cells, while mitosis results in four genetically different cells.

• Meiosis results in four genetically different cells, while mitosis results in two identical daughter cells.

• Meiosis occurs in somatic cells, while mitosis occurs in gametes.

• Meiosis involves one division cycle, while mitosis involves two division cycles.

During which stage of meiosis does crossing over occur?

• Metaphase I

• Anaphase I

• Prophase I

• Telophase I

In which stage of meiosis do sister chromatids separate?

• Anaphase I

• Anaphase II

• Metaphase I

• Metaphase II

What is the significance of crossing over during meiosis?

• It increases genetic variation by exchanging DNA between homologous chromosomes.

• It ensures that each daughter cell receives an identical set of chromosomes.

• It reduces the chromosome number by half.

• It facilitates the attachment of spindle fibers to chromosomes.

Which of the following statements is true about meiosis II?

• It is identical to mitosis.

• It reduces the chromosome number by half.

• It involves the pairing of homologous chromosomes.

• It results in the formation of four diploid cells.

How does meiosis contribute to genetic diversity?

• By producing identical daughter cells.

• Through independent assortment and crossing over.

• By reducing the chromosome number.

• By duplicating the genetic material.

Which phase of meiosis is characterized by the separation of homologous chromosomes?

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

Which of the following best describes the outcome of meiosis?

• Two diploid cells

• Four haploid cells

• Four diploid cells

• Two haploid cells
