Amoeba, yeast, and hydra can reproduce even when only one parent organism is present. Which conclusion does this suggest about asexual reproduction?
It occurs without fusion of gametes.
Amoeba reproduces by binary fission, yeast by budding, and hydra by budding and regeneration. In every one of these methods, a single parent gives rise to offspring without the fusion of male and female gametes. Since no gamete fusion is involved, these are all examples of asexual reproduction.
Asexual reproduction can occur in unicellular organisms (Amoeba, yeast) as well as in some multicellular ones (hydra), so it is not restricted to multicellular offspring. Two parents are not required; that is the defining feature of sexual reproduction. And seeds are needed only in flowering plants, not in these organisms.
Hence, the answer is It occurs without fusion of gametes.
