Expert Answer:

The disadvantage of asexual reproduction arises from the fact that only identical individuals (clones) are produced – there is no variation. Hence an asexually reproducing population that cannot adapt to a changing environment or evolve defences against a new disease is at risk of extinction. Less genetic diversity gives the offspring a lesser chance of survival if the environment changes. Also, asexual reproduction generally leads to overcrowding and a struggle for existence.
