Multiple Choice

During anaphase I of meiosis I, which of the following best describes the behavior of homologous chromosomes?

Sister chromatids are separated and move to opposite poles of the cell.

Chromosomes align individually along the metaphase plate.

Homologous chromosomes are separated and move to opposite poles of the cell.

Homologous chromosomes pair up and undergo crossing over.

Verified step by step guidance

Recall the key events of meiosis I, particularly focusing on anaphase I, to understand chromosome behavior during this phase.

Understand that during anaphase I, homologous chromosomes (each consisting of two sister chromatids) are pulled apart and move to opposite poles of the cell, reducing the chromosome number by half.

Recognize that sister chromatids remain attached during anaphase I and are not separated until anaphase II of meiosis II.

Note that chromosomes align as homologous pairs along the metaphase plate during metaphase I, not individually as in mitosis or meiosis II.

Remember that crossing over occurs during prophase I, not anaphase I, so homologous chromosomes do not pair up or exchange genetic material during anaphase I.
