i. Multicellular eukaryotes such as plants and animals are more phylogenetically diverse than prokaryotes (bacteria and archaea).
ii. All prokaryotes are more closely related to each other than they are to eukaryotes.
iii. Eukaryotic cells tend to be much larger than prokaryotic cells.
iv. Eukaryotic and prokaryotic genomes tend to be about the same size.
v. Eukaryotes and prokaryotes both undergo meiosis.
vi. Eukaryotes and prokaryotes both maintain genetic mechanisms to undergo recombination.
vii. Microbes makes up the majority of cells in the human body.
viii. A humans gut microbial community can be influenced by his/her genetic make-up, but it only rarely affects his/her phenotypic traits.
ix. The vast majority of bacterial species found in or on the human body are neutral or beneficial with respect to their effects on human health.
x. Two strains from the same bacterial species usually share at least 90% of their genes in common.
