Bivalents align on metaphase plate
WebChiasmata are resolved once all bivalent chromosomes aligned well on middle plate and come under microtubule tension leading to anaphase I. Meiosis I is completed by emitting a polar body (PB) containing one set of chromosomes. WebMetaphase I. In metaphase I, each pair of bivalents (two chromosomes, four chromatids total) align on the metaphase plate. This is different from metaphase in mitosis, where all chromosomes align single file on the metaphase plate. The position of each chromosome in the bivalents is random - either parental homolog can appear on each side. This ...
