Question

Clones of sheep are carbon copy of each other exceptphysical health. What kind of variation is it?

Answer 1

Clones are genetically identical individuals.

Clones of sheep are genetically identical individuals, but they may show some physical differences. These kinds of variations are called phenotypic variations. As we all know that phenotype (observable characteristics of an organism) is a result of interaction between genotype ( genetic element) and environment. So, clones of sheep, despite of being genetically similar may show differences in their physical health due to difference in environmental conditions.
