Study Notes
Asexual and Sexual Reproduction in Multicellular Organisms
- Asexual reproduction in multicellular organisms is primarily for growth and repair, not for reproduction
- Invertebrates like sponges, cnidarians, flatworms, annelids, and echinoderms are capable of asexual reproduction
- Examples of asexual reproduction include flatworms splitting in half and sponges regenerating from fragments
- Hydras can reproduce asexually through outgrowths from the parent
- Plants can carry out asexual reproduction through vegetation propagation, such as budding off parts of a plant
- In asexual reproduction, an individual inherits all its chromosomes from a single parent, making it genetically identical to the parent
- Asexual reproduction may be advantageous in a stable environment as it requires lower energy investment and maintains successful parental characteristics
- Sexual reproduction occurs through the union of two cells to form a new individual with genetic variation
- Meiosis and fertilization constitute a cycle of sexual reproduction, bringing about genetic variation in offspring
- Haploid and diploid cells or organisms alternate in the life cycle of organisms in sexual reproduction
- In animals, germ-line cells undergo meiosis to produce haploid gametes, the only stage where the animal maintains its haploid state
- Meiosis brings about genetic variation through crossing over and independent assortment, leading to chromosomally different zygotes in sexual reproduction
