Chapter 13, Problem 3
Meiosis II is similar to mitosis in that
a. Sister chromatids separate during anaphase
b. DNA replicates before the division
c. The daughter cells are diploid
d. Homologous chromosomes synapse
Verified step by step guidance1
Understand the process of Meiosis II: Meiosis II is the second division in meiosis, which follows Meiosis I. It is similar to mitosis in terms of the separation of sister chromatids.
Review the key events of Meiosis II: During Meiosis II, the sister chromatids are separated into different cells, similar to what occurs during mitosis.
Analyze the options given: a) Sister chromatids separate during anaphase, b) DNA replicates before the division, c) The daughter cells are diploid, d) Homologous chromosomes synapse.
Consider the characteristics of mitosis: In mitosis, sister chromatids separate during anaphase, DNA does not replicate before the division, the daughter cells are diploid, and homologous chromosomes do not synapse.
Compare Meiosis II to mitosis: Identify which option describes a process that occurs in both Meiosis II and mitosis, focusing on the separation of sister chromatids during anaphase.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Meiosis II
Meiosis II is the second division in meiosis, where sister chromatids are separated into different cells, similar to mitosis. Unlike meiosis I, it does not involve the separation of homologous chromosomes, and it results in four haploid cells from the two diploid cells produced in meiosis I.

Meiosis II
Sister Chromatids
Sister chromatids are identical copies of a single chromosome that are connected by a centromere. During anaphase of both mitosis and meiosis II, these chromatids are pulled apart to opposite poles of the cell, ensuring that each daughter cell receives an identical set of chromosomes.

Anaphase
Anaphase is a stage in cell division where chromosomes are split and moved to opposite ends of the cell. In mitosis and meiosis II, anaphase involves the separation of sister chromatids, whereas in meiosis I, it involves the separation of homologous chromosomes, highlighting the difference between these processes.

Textbook Question
The diagram shows a cell in meiosis. Label the appropriate structures with these terms: chromosome (label as duplicated or unduplicated), centromere, kinetochore, sister chromatids, nonsister chromatids, homologous pair (use a bracket when labeling), homolog (label each one), chiasma, sister chromatid cohesion, and gene loci, labeling the alleles of the F and H genes.
