Amoeba Sisters Meiosis

What is the primary purpose of meiosis in organisms?

• To produce identical daughter cells

• To reduce the chromosome number by half

• To repair damaged DNA

• To increase the size of the organism

During which phase of meiosis do homologous chromosomes separate?

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

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

• Meiosis results in four daughter cells, while mitosis results in two

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

• Meiosis involves one cell division, while mitosis involves two

• Meiosis produces genetically identical cells, while mitosis produces genetically diverse cells

What is the significance of crossing over during meiosis?

• It increases genetic diversity

• It ensures equal distribution of chromosomes

• It repairs DNA damage
