Meiosis

Question 1

What is meiosis?

Answer 1

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse haploid cells.

Question 2

True or False: Meiosis consists of two rounds of cell division.

Answer 2

True

Question 3

Fill in the blank: Meiosis occurs in ______ cells to produce gametes.

Answer 3

germ

Question 4

What are the two main stages of meiosis?

Answer 4

Meiosis I and Meiosis II

Question 5

During which phase of meiosis does crossing over occur?

Answer 5

Prophase I

Question 6

Multiple choice: Which of the following is a key outcome of meiosis? a) Identical daughter cells b) Genetic diversity c) Increased chromosome number

Answer 6

b) Genetic diversity

Question 7

What is the significance of homologous chromosomes in meiosis?

Answer 7

Homologous chromosomes pair up during meiosis I, allowing for genetic recombination and independent assortment.

Question 8

True or False: Meiosis results in diploid cells.

Answer 8

False

Question 9

What is the term for the exchange of genetic material between homologous chromosomes?

Answer 9

Crossing over

Question 10

Fill in the blank: The final result of meiosis is ______ haploid cells.

Answer 10

four

Question 11

What is the difference between meiosis and mitosis?

Answer 11

Meiosis produces four genetically diverse haploid cells, while mitosis produces two identical diploid cells.

Question 12

During which phase of meiosis do sister chromatids separate?

Answer 12

Anaphase II

Question 13

Multiple choice: Which phase follows Metaphase I? a) Telophase I b) Anaphase I c) Prophase II

Answer 13

b) Anaphase I

Question 14

True or False: Meiosis occurs in both somatic and germ cells.

Answer 14

False

Question 15

What role does the spindle apparatus play in meiosis?

Answer 15

The spindle apparatus helps to separate chromosomes during cell division.

Question 16

Fill in the blank: The process of meiosis contributes to genetic ______ in populations.

Answer 16

variation

Question 17

What are gametes?

Answer 17

Gametes are reproductive cells (sperm and eggs) that are produced by meiosis.

Question 18

During which meiosis phase do the chromosomes align at the cell’s equatorial plane?

Answer 18

Metaphase I and Metaphase II

Question 19

True or False: Meiosis only occurs in animals.

Answer 19

False

Question 20

What is aneuploidy?

Answer 20

Aneuploidy is a condition in which the number of chromosomes is not an exact multiple of the haploid number, often due to errors in meiosis.

Question 21

Multiple choice: Which of the following is NOT a phase of meiosis? a) Prophase b) Metaphase c) Interphase

Answer 21

c) Interphase

Question 22

What is the role of the chiasma during meiosis?

Answer 22

Chiasmata are points where homologous chromosomes exchange genetic material during crossing over.

Question 23

Fill in the blank: The reduction in chromosome number during meiosis is essential for maintaining ______ in sexually reproducing organisms.

Answer 23

genomic stability

Question 24

What happens during Telophase I?

Answer 24

During Telophase I, the nuclear envelope may reform, and the cell divides into two haploid cells.

Question 25

True or False: Each daughter cell produced by meiosis is genetically identical to the parent cell.

Answer 25

False

Question 26

What is the primary purpose of meiosis in sexual reproduction?

Answer 26

The primary purpose is to produce gametes with half the number of chromosomes for fertilization.
