Final answer:
Each pair of paternal chromatids seeks out their homologous chromosomes during metaphase I of meiosis, aligning along the cell's equator before being separated into gametes.
Step-by-step explanation:
During cell division, specifically in metaphase I of meiosis, each pair of paternal chromatids seeks out their homologous chromosomes. This is when spindle fibers attach to the paired homologous chromosomes, allowing them to align along the equator of the cell. It is important to note that this process only occurs in metaphase I of meiosis. In contrast, during metaphase of mitosis and meiosis II, it is the sister chromatids that line up along the cell's equator.
The correct answer to the student's question is A) Homologous chromosomes. This alignment is crucial as it ensures that each gamete receives one of the two homologous chromosomes, contributing to genetic diversity in the resulting gamete.
