how can the random factors involved in some of the steps of meiosis ca contribute to genetic drift?

Answer 1

Let's say that during meiosis or mitosis, an electron of background radiation (it's everywhere) comes into contact with a chromosome - it could change the chromosome or destroy it entirely, contributing to genetic drift.

Also think of things in this way too - not all cells contain the same information. Let's take your parents for example...they had you, and you look the way you do...then, they have another child - that child looks different than you do - so not all cells are the same - multiple cells inside an organism can together, create genetic drift as well.
