Pros and cons of asexual reproduction through binary fission
Disadvantages of Sexual Reproduction Reproduction cannot occur until and unless gametes from both parents fuse together. This pollen like a sperm in animals, travels down the style and fertilizes the eggs in the ovaries. Advantages of Sexual Reproduction Sexual reproduction involves two organisms of the same species, thus leading to formation of gamete cells.
Sexual reproduction takes place only after the male and female mate. The diploid copy of genes favors evolution of a dominant species with less number of mutations and genetic defects. It is possible to observe sexual reproduction in plants. Disadvantages of Asexual Reproduction As the genetic material from parent is directly passed on to the off spring, it causes all the diseases and defects to be passed on to the offspring as well.
These two methods are used by plants and animals to ensure their species continues to survive. Advantages of Sexual Reproduction Sexual reproduction involves two organisms of the same species, thus leading to formation of gamete cells. It is possible to observe sexual reproduction in plants. According to the various species, these methods prove to be a successful way to sustain life.
For example, bacteria can undergo conjugation, hydra and yeast can reproduce sexually. Asexual Reproduction in Animals. This progeny produced is totally identical to the parent in its genetic makeup. This embryo develops into a seed that on germination will develop into a new plant.
Some flowers can be hermaphrodites, that is, contain both male and female organs. The cells undergo meiosis and produce haploid cells n. Asexual Reproduction in Plants. Pros and Cons of Cloning.
