Question

Quizplus · Accepted Answer

The presence of both haploid and diploid phases in the life cycle of a species of fern is an example of alternation of generations, where the organism alternates between the two phases during its life cycle. The haploid phase produces gametes through mitosis, which fuse during fertilization to form a diploid zygote, which then grows into a multicellular diploid phase that produces spores through meiosis, and the cycle repeats. This is different from haplontic life cycles, where only the haploid phase is multicellular, and diplontic life cycles, where only the diploid phase is multicellular. Asexual reproduction and independent assortment are not related to the presence of both haploid and diploid phases in the life cycle of a species.
