Verified step by step guidance

Understand that pairing of homologous chromosomes is a key feature of meiosis, specifically during Prophase I, where homologous chromosomes undergo synapsis to form tetrads.

Recall that during Metaphase I of meiosis, homologous chromosome pairs align at the metaphase plate, but the pairing has already occurred earlier in Prophase I.

Recognize that Anaphase I of meiosis involves the separation of homologous chromosomes, so pairing no longer occurs at this stage.

Know that mitosis is a type of cell division where homologous chromosomes do not pair; instead, sister chromatids separate to produce genetically identical daughter cells.

Conclude that the stage during which no pairing of homologous chromosomes occurs is mitosis, as pairing is unique to meiosis and specifically to early stages like Prophase I.
