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.
WebDuring metaphase I the bivalents (pairs of homologous chromosomes) are organized along the metaphase plate. During anaphase I, the homologous chromosomes (paired … WebDuring metaphase I, a spindle apparatus forms and the paired chromosomes align along the equatorial pole of the cell. During anaphase I, the individual bivalents completely separate from each other; then homologous chromosomes, with their cognate centromere, are separated and drawn to opposite poles of the cell.
