Question 1

Which phase of meiosis is depicted in the first image, where 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, replicated chromosomes

Question 3

If the cell in the second image undergoes meiosis I, what will be the number of chromosomes and their replication status in each resulting daughter cell?

Accepted Answer

2 chromosomes, replicated

Question 4

During which stage of meiosis do homologous chromosomes separate, as shown in the first image?

Accepted Answer

Anaphase I

Question 5

If a cell starts with 4 replicated chromosomes as shown in the second image, how many total chromatids are present in the cell?

Accepted Answer

$$16$$

Question 6

After meiosis II, what would be the chromosome number and ploidy of each cell derived from the cell in the second image?

Accepted Answer

2 chromosomes, haploid

Question 7

Which of the following best describes the arrangement of chromosomes in the second image?

Accepted Answer

Two pairs of homologous chromosomes, each with two sister chromatids

Question 8

If nondisjunction occurs during the stage shown in the first image, what is the likely result in the gametes?

Accepted Answer

All gametes will have an abnormal number of chromosomes

Question 9

Which process ensures genetic diversity during the formation of gametes, as represented by the arrangement of chromosomes in the second image?

Accepted Answer

Crossing over during prophase I

Question 10

If the cell in the second image is from a species with a diploid number of 4, what is the haploid number for this species?
