Answer:
Eukaryotic genetic variation occurs with VERTICAL gene transfer while prokaryotic genetic variation occurs with HORIZONTAL gene transfer
Explanation:
In Eukaryotes, genes lays on top of each since they reproduce sexually this gives rise to their genetic variation and hence the vertical gene transfer, but prokaryotes lie side by side, reproducing by conjugation, transformation and transduction. This makes their genetic variation to be horizontal.
Example is conjugation in Spirogyra.
This question is really opinion based, but I would take it personal when things go wrong, since I start to think what I didn't or did do that made things go wrong.
