Which mode of reproduction is characteristic of organisms in the kingdom Animalia?

Explanation:
Sexual reproduction is the mode most animals use. In animals, offspring typically arise from two parents who produce specialized sex cells—sperm and eggs. When these gametes unite during fertilization, a zygote forms and develops into an organism, bringing genetic variation into the next generation. This variation helps populations adapt over time. Some animals can reproduce asexually in certain cases—through methods like budding or fragmentation—but these are not the general pattern for life in Animalia. Therefore, sexual reproduction best describes the characteristic mode for this kingdom.
