Asexual reproduction is a process where an organism creates one or more offspring genetically identical to itself without the involvement of gametes. Three key features of asexual reproduction include: the offspring are clones of the parent, which leads to little genetic diversity; it typically occurs rapidly and can result in large numbers of offspring; and it requires only one parent, making it efficient in stable environments.
In contrast, sexual reproduction involves the combination of genetic material from two parents, typically through the fusion of male and female gametes. Three defining features of sexual reproduction are: it promotes genetic diversity due to the mixing of genes, which can enhance adaptability; it usually involves complex courtship and mating behaviors; and it often requires more time and energy than asexual reproduction, as finding a mate and developing offspring can take longer.
