A biologist observes a dividing cell under a microscope and notes that the synaptonemal complex has dissolved. The recombined homologous chromosomes of the bivalents have separated from each other, except at specific X-shaped regions where they remain attached. Identify the stage of cell division this cell will enter NEXT, along with the primary event that characterizes it.

Step-by-step solution

The cell described is currently in the diplotene stage of prophase I. This stage is recognised by the dissolution of the synaptonemal complex and the tendency of recombined homologous chromosomes to separate from each other except at the sites of crossovers (forming X-shaped chiasmata). The question asks for the stage the cell will enter NEXT. The stage following diplotene is diakinesis. Diakinesis is characterised by the terminalisation of chiasmata, where the chiasmata move towards the ends of the chromosomes. An
