WebWithin the spindle, the bivalents are aligned in a pentagonal array with the X chromosome in the center ( Albertson and Thomson, 1993 ). The first meiotic division, which segregates chromosome homologs, is completed in approximately 15 min with the ejection of the first polar body (with a 2 n ploidy) during anaphase I.
