Amoeba Sisters En Espanol: Meiosis

What is the primary purpose of Meiosis?

• To produce energy for cellular functions.
• to increase genetic variation

• To repair damaged tissues in the body.
• To create identical daughter cells for growth.

How many chromosomes do human gametes have?

• 22
• 46
• 44
• 23

What happens during interphase before meiosis begins?

• DNA is duplicates

• The cell loses its DNA and prepares for apoptosis

• The cell undergoes cytokinesis and divides into two cells

• The cell enters a resting phase and stops all activity.

What significant event occurs during prophase I of meiosis?

• Crossing over occurs between homologous chromosomes.
• Nuclear envelope breaks down
• Chromosomes align at the equator
• DNA replication occurs

During which stage of meiosis I do chromosomes align in the middle of the cell in pairs?

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

What is the main difference between metaphase I and metaphase II?

• In metaphase I, individual chromosomes align; in metaphase II, homologous chromosomes align in pairs.
• In metaphase I, chromosomes are replicated; in metaphase II, they are not.
• Chromosomes are in single file in Metaphase I

• Chromosomes are in pairs in Metaphase I

How many cells are produced at the end of meiosis II?

• 2
• 4
• 6
• 8

What is the result of independent assortment and crossing over during meiosis?

• No effect on genetic diversity.
• Increased genetic variation in gametes.
• Formation of identical gametes.
• Decreased genetic variation in gametes.

What is nondisjunction in the context of meiosis?

• Nondisjunction is the failure of chromosomes to separate during meiosis.
• Nondisjunction refers to the separation of sister chromatids in mitosis.
• Nondisjunction is the process of chromosome duplication during meiosis.
• Nondisjunction is the alignment of chromosomes at the metaphase plate.

Why might two siblings with the same parents look different from each other?

• One sibling is a clone of the other.
• They develop from different gametes

• They were raised in different countries.
• They inherited the same eye color from their grandparents.
