Chlamydiae together with mycoplasmas, constitute the bacterial species with the smallest genomes, possibly because they are obligate small intracellular parasites for a long time, which has allowed them to lose certain metabolic pathways, however, they contain DNA, RNA and ribosomes therefore synthesize their own proteins and nucleic acids. Chlamydiae have a unique biphasic life cycle: the elemental body, which is the infectious form, and the reticular body, which is the replicative and metabolically active form that possesses a fragile membrane that lacks the extensive disulfide bonds characteristic of elemental bodies. The characteristics of its biological cycle do not facilitate the possibility of exchange and acquisition of exogenous genetic material.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
