The correct option is A It produces genetically uniform populations.
Asexual reproduction produces off springs which are similar (clones) and no genetic variation is seen as in sexual reproduction. Variations are necessary for evolution.
The following are adavantges of asexual reproduction. However, asexual reproduction allows an organism to produce many offspring quickly. It saves the time and energy of gamete production and it allows organisms which do not move around to produce offsprings. Mating is not necessary. Producing clones is also an advantage for commercial food production.
