How do you know if a cell is reproducing asexually when it divodes?

Mitosis, fission, budding, fragmentation etc are all asexual and don’t require fertilization. Meiosis is sexual and generally requires another gene set for internal or external fertilization, to create genetically variable gametes.

I think the answer would be that the two cells are identical and that no other cell interfered. Sorry if this is wrong, I took biology in 7th grade, so it's kind of fuzzy.
