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 asexual reproduction include: it does not lead to variation in a population. the species may only be suited to one habitat. disease may affect all the individuals in a population.

Detailed explanation-3: -Sexual reproduction requires exponentially more energy than asexual reproduction. Nevertheless, sexual reproduction has two major advantages over asexual reproduction: it results in genetic diversity in offspring, and it eliminates harmful mutations.

Detailed explanation-4: -Features of Sexual Reproduction Two parents are involved (both male and a female). Gamete formation and fertilization take place. The whole process is slow and lengthy. Variation occurs; offspring are different from parents, genetically and physically.
