NEET BIOLOGY

Detailed explanation-1: -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-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: -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.

Detailed explanation-4: -Loss of genetic diversity increases the risk of extinction of a population through inbreeding depression. In addition, the number of deleterious genetic variations, which might accumulate in a small population through genetic drift, can also make the population vulnerable.

Detailed explanation-5: -Another hypothesis states that because asexual reproduction limits genetic diversity within a species, the animals eventually become unable to adapt to changes in the environment. “The expectation is that these asexual organisms are at a genetic disadvantage, ” said Warren, also an assistant professor of genetics.
