Explanation

Alternation of generations may be defined as a phenomenon whereby, in the life history of an organism, a diploid asexual phase and a haploid sexual phase regularly alternates with each other. This type of true alternation of generation is also called metagenesis. In coelenterates, an asexual polypoid generation appears to alternate reqularly with a sexual medusoid generation.
