Regarding prokaryotic reproduction, which statement is correct? Prokaryotes exchange some of their genes by conjugation, the union of haploid gametes, and transduction. Mutation is a primary source of variation in prokaryote populations. Prokaryotes skip sexual life cycles because their life cycle is too short. Prokaryotes form gametes by meiosis. Prokaryotes feature the union of haploid gametes, as do eukaryotes.
