The dominant phase in the life cycle of a fern is the sporophyte. This is because the sporophyte is the diploid phase, which means that it has two sets of chromosomes. The sporophyte is the leafy plant that we see when we look at a fern, and it is the stage that produces spores through meiosis. The spores then develop into the haploid gametophyte stage, which is much smaller and is not visible to the naked eye. The gametophyte produces gametes (sperm and eggs) that then fuse to form the diploid zygote, which develops into the sporophyte.
