Question

what do you mean by metagenesis​

Answer 1

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.

Answer 2

Metagenesis is another term for generational alternation.

Explanation:

• The phenomenon of metagenesis occurs when one generation of some plants and animals reproduces asexually, succeeded by the sexually reproducing generation.

• It is a phenomenon in which an organism's life cycle alternates between a diploid asexual phase and a haploid sexual phase.

• Plants such as mosses and ferns exhibit this form of real alternation of generation. A multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs in these groupings.
