Multiple Choice
Mitosis is most similar to which stage of meiosis in terms of chromosome behavior (i.e., sister chromatids separate and the chromosome number is maintained)?
A
Meiosis I (anaphase I), when homologous chromosomes separate
B
Meiosis II (anaphase II), when sister chromatids separate
C
Telophase I, when two haploid nuclei form after homologs have separated
D
Prophase I, when synapsis and crossing over occur
Verified step by step guidance1
Recall that mitosis involves the separation of sister chromatids to produce two genetically identical daughter cells, maintaining the chromosome number.
In meiosis, there are two divisions: Meiosis I and Meiosis II. Meiosis I separates homologous chromosomes, reducing the chromosome number by half.
Meiosis II resembles mitosis because it separates sister chromatids, similar to what happens during mitosis.
Identify the stage in meiosis where sister chromatids separate: this occurs during anaphase II of meiosis.
Therefore, mitosis is most similar to meiosis II (anaphase II) in terms of chromosome behavior, where sister chromatids separate and chromosome number is maintained.
