Chromonemata start associating into bivalent chromosomes during

When synapsis is complete all along the chromosome,the cells are said to have entered a stage of prophase $I$,where exchange of genetic material takes place between homologous chromosomes. The stage is called

In which sub-stage of Prophase-$I$ does the "Bouquet stage" occur?

$S -$ Statement: Recombination nodules are visible during the diplotene stage.
$R -$ Reason: Synapsis occurs during the zygotene stage.

The homologous chromosomes follow the process of synapsis in the stage or Pairing of homologous chromosomes takes place in:

In meiosis,the daughter cells are not identical to the parent cells because of .........
