|
|
|
There is great variation among offspring.
|
|
|
Offspring will get all good characteristics of parents.
|
|
|
Offspring have difficulty in adapting to new environment.
|
|
|
Adapting to the environment is always constant among the offspring.
|
Detailed explanation-1: -In asexual reproduction, the offspring is an exact copy of the parent since only one parent is involved in reproduction. Therefore, there is no variation in the organisms and they have fewer chances to adapt to different environments.
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: -In an unstable or unpredictable environment, species that reproduce asexually may be at a disadvantage because all the offspring are genetically identical and may not be adapted to different conditions.
Detailed explanation-4: -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.
