Asexual reproduction is a mode of reproduction that involves a single parent organism producing offspring that are genetically identical to itself. Key features of asexual reproduction include its efficiency, as it typically occurs rapidly and requires less energy; the lack of gamete formation, meaning no sex cells are involved; and the ability of organisms to reproduce in stable environments where they are well-adapted.
In contrast, sexual reproduction involves two parent organisms contributing genetic material to produce genetically diverse offspring. This process usually involves the formation of specialized sex cells, or gametes, through meiosis; it often requires more energy and time due to the mating behaviors and processes involved; and it promotes genetic diversity, which can enhance the adaptability of a species in changing environments.
