Question

Which of the following occurs during anaphase I
Options
A Chromosomes cluster at the two poles of the cell
B Crossing over occurs
C Chromosomes align down the center of the cell
D One version of each chromosome moves towards a pole
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

During anaphase I of meiosis, homologous chromosomes separate and are pulled to opposite poles of the cell. Each pole receives one version of each chromosome (one from each homologous pair), which still consists of two sister chromatids. Option A describes telophase I. Option B is prophase I. Option C is metaphase I.

Hint

What separates in anaphase I: homologous chromosomes or sister chromatids?
