Bivalents are formed during meiosis when homologous chromosomes pair up (synapsis) in prophase I. Each bivalent consists of two homologous chromosomes, each having two chromatids. During metaphase I of meiosis, these bivalents align on the equatorial plane (metaphase plate) of the cell.
In anaphase I, homologous chromosomes separate and move towards opposite poles, so alignment is no longer seen. In mitosis, homologous pairing does not occur; instead, individual chromosomes align at the equator during metaphase.
Hence, bivalents specifically align at the equator during metaphase I of meiosis.
