The process of Meiosis itself can increase genetic diversity within a population

The process of Meiosis itself can increase genetic diversity within a population. (A) state what specific events in meiosis lead to diverse offspring, (B) refer to the specific steps/stages of meiosis when these events take place, AND (C) explain how these events relate to Mendel’s Laws of Segregation and Assortment.

Please help.. this is what I have so far.

(A) crossing over take place during meiosis and that is the reason leads to diverse offsprings.

genetic recombination also a way which leads to diverse offsprings.

(B) crossing over takes place at metaphase stage of division while all chromosomes pairs are lined up at the center line of the cell.

genetic recombination occurs at pachytene stage of prophase of meiosis.
