In meiosis you can have:

Crossing over( sections of the chromosome break and rejoin forming a new DNA pattern)
Independent assortment( chrosomsomes randomly align)

 Random selection of mating partner also means that each time, there will be different chromosomes with different partners.

So in independent assortment, is that is metaphase, when they line up on the equator of the cell?

Thankyou!!!

yes, when they line up, they could do so in any order meaning there's a lot of variation in the outcomes  :):)
