The term "Clone" is used to describe the offspring that are :

Morphologically and genetically identical

In asexual reprodution, a single parent is involved in producing the offspring. It occurs without the formation and fusion of gametes. As a result, the offspring that are produced are not only morphologically and genetically identical to one another but are also exact copies of their parents. The term clone is used to describe such morphologically and genetically similar individuals. Therefore the offspring produced by asexual reproduction are called clones.
