Final answer:
Homologous pairs of chromosomes align along the metaphase plate during metaphase I of meiosis, which ensures genetic diversity through the random assortment of chromosomes.
Step-by-step explanation:
During metaphase I of meiosis, homologous pairs of chromosomes align along the metaphase plate. This phase is crucial in the process of meiosis I as it ensures that each new cell will receive one chromosome from each homologous pair. This alignment allows for the random assortment of chromosomes, which contributes to genetic diversity. In contrast, metaphase II involves the alignment of sister chromatids along the metaphase plate, preparing them for separation.
