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: -The disadvantages of sexual reproduction include: (1) Finding a mate uses valuable resources (such as time and energy). (2) It is not possible for an isolated individual to reproduce sexually. As asexual reproduction can be done by an individual the above problems are not present.
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.
