What is alternation of generation? |
| Answer» Alternation of generations, also called metagenesis or heterogenesis, in biology, the\xa0alternation\xa0of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or\xa0generations, are often morphologically, and sometimes chromosomally, distinct.\xa0The fern is an\xa0example of alternation of generations, in which both a multicellular diploid organism and a multicellular haploid organism occur and give rise to the other. ... The large, leafy fern is the diploid organism. On the undersurface of its fronds or leaves, its cells undergo meiosis to create haploid cells. | |
