1.Selected Answer: 1. Sexual reproduction is bi-parental and gametic cells are involved, while asexual reproduction is uni-parental and involves somatic cells. 2. Offsprings are similar in asexual reproduction, while in sexual reproduction, offsprings are genetically different. 3. The rate of reproduction of asexual reproduction is faster than that of sexual reproduction. 2.Selected Answer: Budding: In budding, a new organism originates from outgrowth or bud due to cell division. Bacteria is an example. Fission: In this type of asexual reproduction, an organism separates and divides into two new bodies, and division occurs after copying genetic material. In bacteria, binary fission occurs, Fragmentation: an organism divides into fragments, and each fragment becomes a new organism; Seastar is an example of fragmentation as a means of asexual reproduction. Parthenogenesis: The self-impregnation of an organism with the production of the zygote from an unfertilized egg. Bees are examples. 3.Asexual reproduction offsprings are exact replicas of parent organisms, and similar genomes do not cause adaptation to adjust to changing environments. In contrast, sexual reproduction provides an opportunity to produce changes in genomes, and adaptation to changing environmental conditions is more suitable in the case of sexual reproduction.
