Verified step by step guidance

Understand the context of metaphase in both meiosis and mitosis. In metaphase, chromosomes align at the metaphase plate, which is an imaginary plane equidistant from the two spindle poles.

In metaphase of mitosis, sister chromatids line up at the metaphase plate. Each chromosome is composed of two sister chromatids joined at the centromere, and they are aligned such that each chromatid is oriented towards opposite poles.

In metaphase I of meiosis, homologous chromosomes, also known as tetrads, line up at the metaphase plate. A tetrad consists of two homologous chromosomes, each made up of two sister chromatids, for a total of four chromatids.

Recognize that centromeres are the part of a chromosome that links sister chromatids. During metaphase, centromeres are crucial for the attachment of spindle fibers but are not what specifically lines up at the metaphase plate.

Identify that the key difference between metaphase in mitosis and metaphase I in meiosis is the alignment of sister chromatids in mitosis and homologous chromosomes (tetrads) in meiosis I. Therefore, the correct answer for what lines up at the metaphase plate during metaphase I of meiosis is 'tetrads' or 'homologous chromosomes'.
