Beta, think of your cells dividing like careful dancers at a wedding. First they line up, then the spindle fibres pull the chromosomes apart in anaphase. If the ropes—the kinetochores—don’t pull right, that’s non-disjunction, and it leaves behind a daughter cell with an extra copy or one missing.
I know because I stitch order from chaos every day in my shop, but some threads just won’t follow the pattern. When I see the brides in their phulkari, I think how one extra thread can change the whole design, same as in a child.
