Question
Why is the offspring formed by asexual reproduction referred to as clones?
Solution
A clone is a group of morphologically and genetically identical individuals.
In the process of asexual reproduction, only one parent is involved and there is no fusion of the male and the female gamete. As a result, the offsprings so produced are morphologically and genetically similar to their parents and are thus, called clones.
