example of metagenesis

The definition of metagenesis is the reproduction cycle of an organism that alternates between sexual and asexual generations. An example of metagenesis is the reproduction cycle of a cnidarian.

What do you mean by Metagenesis give one example of animal that shows Metagenesis?

Metagenesis is referred to the phenomenon of alternation of generation shown by cnidarians which exhibit both forms- polyps and medusae . Polyps produce medusae asexually and medusae form the polyps sexually (e.g., Obelia).

What is Metagenesis mention an example which exhibits this phenomena?

Both the forms are diploid in metagenesis hence, it is the false alternation of generation. Coelenterates exhibits metagenesis (e.g., Obelia) where polyp form alternates with medusa in its life cycle.

Does Hydra show Metagenesis?

Complete Answer:

Hydra shows only asexual mode of reproduction via budding. As there is no sexual reproduction, metagenesis is not possible in case of Hydra.

Which of the following animals exhibit Metagenesis?

metagenesis is the alternation in generation of sexual and asexual reproduction. It is exhibited by Obelia , of phylum Coelentrata .

What is Metagenesis and example?

The definition of metagenesis is the reproduction cycle of an organism that alternates between sexual and asexual generations. An example of metagenesis is the reproduction cycle of a cnidarian. ... (biology) The production of sexual and asexual organisms in alternate generations.

What do you mean by Metagenesis give an example?

Metagenesis is the phenomenon in which one generation of certain plants and animals reproduce asexually, followed by the sexually reproducing generation. ... Coelenterates exhibits metagenesis (e.g., Obelia) where polyp form alternates with medusa in its life cycle.

What are the two stages of Metagenesis?

Alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.

What is Metagenesis in cnidaria?

Some cnidarians exist in polyp and medusa forms. Such cnidarians show metagenesis. It is the phenomenon of alternation of generations in which polyps produce medusae asexually and medusae produce polyps sexually. Metagenesis is observed in Obelia.

What is Metagenesis in obelia?

METAGENESIS The life cycle of Obelia represents a remarkable example of alternation of generation where the asexual and sessile phase of Obelia reproduces asexually by budding and gives rise to sexual and free-swimming medusa. ... This phenomenon of alternation between two diploid phases is termed as metagenesis.

Where is Metagenesis found?

Metagenesis can be seen in physalia.

Metagenesis is a process which takes place in algae and primitive plants. Here the plant is able to perform both sexual and asexual reproduction.

Which Coelenterate is not polymorphic?

Hydra is also a coelenterate but fails to exhibit polymorphism, this is not the correct answer. Planaria is Platyhelminthes and is not considered as Coelenterata and these are not an answer.

Is Metagenesis seen in jellyfish?

Polyp produce medusae sexually and medusae form the polyp asexually (e.g., Obelia). (d). Metagenesis is seen in jelly fish. ... Polyps produce medusae sexually and medusae form polyps asexually.
