Detailed explanation-1: -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.

Detailed explanation-2: -The biggest disadvantage of asexual reproduction is lack of diversity. Because members of an asexually reproducing population are genetically identical except for rare mutants, they are all susceptible to the same diseases, nutrition deficits, and other types of environmental hardships.

Detailed explanation-3: -Asexually reproducing organisms spend fewer resources for the same reproductive output, meaning their populations grow and expand faster than sexually reproducing ones. On the other hand, asexual populations have reduced genetic diversity and, hence, lower adaptability to changing environments.

Detailed explanation-4: -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-5: -Hence, the correct answer is option B, ‘Lack of genetic variation’. Note:Asexual reproduction is less costly in terms of energy and time expenditure. Though asexual reproduction can occur in various types of environment, any type of change can lead to their destruction.
