Question 1

Which phase of meiosis is depicted in the first image, where homologous chromosomes are being pulled toward opposite poles of the cell?

Accepted Answer

Anaphase I

Question 2

In the second image, the cell contains two pairs of homologous chromosomes, each consisting of two sister chromatids. What is the ploidy and replication status of this cell?

Accepted Answer

Diploid with replicated chromosomes

Question 3

During which stage of meiosis do homologous chromosomes pair up and exchange genetic material through crossing over?

Accepted Answer

Prophase I

Question 4

If a cell starts meiosis with 4 chromosomes (2 pairs of homologous chromosomes), how many chromosomes will each daughter cell have at the end of meiosis II?

Accepted Answer

$$2$$

Question 5

Which of the following best describes the difference between mitosis and meiosis I?

Accepted Answer

Homologous chromosomes separate in meiosis I, but not in mitosis

Question 6

A cell with the chromosome configuration shown in the second image is about to undergo which process?

Accepted Answer

Meiosis I

Question 7

If nondisjunction occurs during anaphase I of meiosis, what is the likely outcome for the resulting gametes?

Accepted Answer

All gametes will have an abnormal number of chromosomes

Question 8

Which of the following statements about homologous chromosomes is correct?

Accepted Answer

They carry the same genes but may have different alleles

Question 9

What is the main purpose of crossing over during meiosis?

Accepted Answer

To increase genetic diversity in gametes

Question 10

Which of the following best explains why the chromosome number is halved during meiosis?

Accepted Answer

To ensure that fertilization restores the diploid number

Question 11

If a diploid cell with 4 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?

Accepted Answer

$$4$$

Question 12

Which enzyme is responsible for joining Okazaki fragments on the lagging strand during DNA replication?

Accepted Answer

DNA ligase

Question 13

A cell in metaphase I of meiosis has chromosomes aligned at the metaphase plate. What is the configuration of these chromosomes?

Accepted Answer

Homologous pairs aligned side by side

Question 14

Which of the following events occurs only during meiosis and not mitosis?

Accepted Answer

Crossing over between homologous chromosomes

Question 15

If a cell has 2 pairs of homologous chromosomes (as shown in the second image), how many possible combinations of chromosomes can result in the gametes due to independent assortment?

Accepted Answer

$$2^2 = 4$
