|
|
|
a lot of time and energy is required for making gametes (egg and sperm cells) and finding mates
|
|
|
offspring (children) can be produced more quickly than by asexual means
|
|
|
the genetic diversity makes organisms respond differently to environmental changes
|
|
|
the offspring (children) are genetically different
|
Detailed explanation-1: -A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.
Detailed explanation-2: -Since asexual reproduction does not involve meiosis and fusion of gametes, the offspring are genetically similar to parents and they do not show variations. Additional information: Asexual reproduction occurs without the formation of sex organs. It does not involve meiosis or reduction division.
Detailed explanation-3: -The major disadvantages of asexual reproduction are: Lack of diversity-Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.
