Process of Meiosis

What is the primary function of meiosis compared to mitosis?

• To create gametes with half the number of chromosomes

• To increase the number of body cells

• To repair damaged cells

• To create identical body cells

What happens to the chromosome number during meiosis?

• It remains the same

• It increases fourfold

• It reduces by half

• It doubles

What is crossing over and why is it important?

• It's the separation of homologous chromosomes, reducing genetic errors

• It's the replication of DNA, speeding up cell division

• It's the exchange of chromosome segments, increasing genetic diversity

• It's the duplication of chromosomes, ensuring genetic stability

During which phase do homologous chromosomes line up in the middle of the cell in meiosis I?

• Anaphase I

• Metaphase I

• Prophase I

• Telophase I

What is the result of meiosis I?

• Four haploid cells

• Two diploid cells

• Four diploid cells

• Two haploid cells

What does the Law of Independent Assortment state?

• Genes replicate independently of each other

• Chromosomes are sorted based on their size

• Genes are sorted independently during meiosis I

• Chromosomes are duplicated independently

What occurs during prophase II of meiosis?

• Chromosomes duplicate

• Nuclear membrane breaks down

• Chromosomes increase in number

• Cell undergoes cytoplasmic division

How many rounds of cell division does meiosis include?

• Three

• Two

• Four

• One

What is the end result of meiosis II?

• Two haploid cells

• Four haploid cells

• Four diploid cells

• Two diploid cells

How does meiosis contribute to genetic diversity?

• By mechanisms like crossing over and independent assortment

• By creating identical cells

• By reducing chromosome number by half

• By undergoing two rounds of cell division
