WebJun 13, 2024 · The gametophyte is a haploid organism, containing only one set of DNA. The gametes, therefore, are produced via mitosis. When these gametes fuse, they create a zygote, which is a new diploid organism. This zygote will grow up into the sporophyte generation. The sporophyte generation is responsible for producing spores. WebDuring gametophyte development, endosporic gametophytes are dependent on their sporophyte parent. The development of the gametophyte within the spore wall directly reduces the environmental impacts on the gametophytic gene expression resulting in higher genetic variation and rates of diversification.
