Which type of division results in polyploidy?

In which phase of meiosis do the chromatids separate and move towards opposite poles?

Match the following columns:

Column $I$	Column $II$
$(a)$ Prophase-$I$	$(p)$ Nucleolus and nuclear membrane reappear
$(b)$ Metaphase-$I$	$(q)$ Longest phase
$(c)$ Anaphase-$I$	$(r)$ Homologous chromosomes align at the equatorial plate
$(d)$ Telophase-$I$	$(s)$ Number of chromosomes reaching each pole is half of the original cell

$A$ : Anaphase-$I$ is the actual phase of reduction in the number of chromosomes.
$R$ : Homologous chromosomes move to the opposite poles with both their chromatids.

List the phases of meiosis.

In oocytes of some vertebrates,this stage can last for months or years.
