- Self-fertilization, or selfing, seems to have obvious disadvantages as a reproductive “strategy” in nature, and ithas even been called an “evolutionary dead end.” So it issurprising that about 20% of angiosperm species primarily rely on selfing. Suggest a reason why selfing might beadvantageous and yet still be an evolutionary dead end.arrow_forwardDiscuss the life cycle of the brown algae Laminaria, which shows the alternating of generations.arrow_forwardThe number of taxa exhibiting asexual reproduction is drastically reduced in the higher plants (angiosperms) and higher animals (vertebrates) as compared with lower groups of plants and animals. Analyse the possible reasons for this situation.arrow_forward

Make sure to indicate whether each stage in the life cycle is haploid or diploid, and unicellular or multicellular. Also write the stage's name (e.g., zygote, gametophyte, spore, etc.) if it has one. You don't need to draw the stages - e.g., for a zygote you can just write "zygote, unicellular, 2N". Also make sure to indicate where exactly in the life cycle meiosis takes place. Please draw and label these as possible clearly as Haplontic Diplontic Alternation of generationsarrow_forward
