D
Anaphase I
Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two stages: Meiosis I and Meiosis II.
Recognize that during Meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated into two different cells.
Recall the stages of Meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I.
In Anaphase I, homologous chromosomes are pulled apart by spindle fibers and move toward opposite poles of the cell. This is the key event that distinguishes Anaphase I from other stages.
Conclude that the stage during which homologous chromosomes move to opposite poles in Meiosis I is Anaphase I.
