Hydra are marine organisms that reproduce by the offspring, simply, growing out of the parent organism. The parent organism does not require a mate, and therefore, genetic variation is reduced. Which choice best describes this form of reproduction

Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out is called a Bud. The new organism remains attached as it grows, separating from the parent organism only when it is mature, leaving behind scar tissue. Since the reproduction is asexual, the newly created organism is a clone and mutations is genetically identical to the parent organism thereby genetic variation is reduced.

Organisms such as hydra use regenerative cells for reproduction in the process of budding.

In hydra, when conditions are favourable, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.

It is when conditions are not favourable, often during timid weather conditions or in poor feeding conditions, Hydra undergoes sexual reproduction. Swellings in the body wall develop into either ovaries or testes. The testes release free-swimming gametes into the water, and these can fertilize the egg in the ovary of another individual. The fertilized eggs secrete a tough outer coating, and, as the adult dies, these resting eggs fall to the bottom of the lake or pond to await better conditions, whereupon they hatch into nymph Hydra.

Answer:

Asexual reproduction (budding)

Explanation:

Asexual reproduction is a form of reproduction that does not require sexual relation. A sexually reproducing organism makes a copy of itself without swapping any genetic information with a mate.

There are different types of asexual reproduction:

Binary fission: organism makes a copy of its genetic materials and then split into two, donating a copy of the genetic material into each of the cells.
Budding: Organism splits off a small portion of itself. The small portion eventually becomes independent and becomes a new organism.
Vegetative propagation: When a plant cell/tissue/organ becomes a new independent plant
Fragmentation: Organism splits into several parts and each part becomes a new organism.
Sporogenesis: Organism produce spores which are capable of germinating to become new organisms.
Agamenogenesis: Reproduction without fertilization

In hydra, the offspring starts as a young bud on the parent before eventually getting detached to become a new independent organism.
