Identify the stage of meiosis shown in the figure.

$A-$ In meiosis,during anaphase $I$,homologous chromosomes move to the opposite poles.
$R-$ Each pole receives half the number of chromatids in anaphase $I$.

In higher animals,the process of crossing over,which results in genetic recombination,occurs between which of the following?

Haploid $(n)$ cell formation from diploid $(2n)$ cell is known as.......

Meiosis in a cell results in the formation of ............ . (in $cells$)

Which process involves the exchange of genetic material between non-sister chromatids?
