Correct answer: B). Genetic diversity
Asexual reproduction is a form of reproduction that gives rise to offspring from a single organism and transfers the similar gene as that of a parent to the offspring, there is no fusion of gametes and crossing over. As a result of that, there is no variation in the offspring from one generation to another generation.
It means that all the individual has the same genetic makeup, means there is no genetic diversity, which is required to survive in odd environmental condition and it leads to evolution.
