What are the advantages and Disadvantages of Variation??
The advantages of variation are as follows :
- It provides basis of evolution
- It helps in maintaining life even in adverse conditions, as some individuals having variation can even survive in adverse environment. So, natural selection will result in survival of the species having variation which makes it better than others.
The variation can be disadvantageous only when it occurs at individual level. For example, the variation that arises from mutation can be lethal for the organisms. So, organisms which such kind of variation will not survive.
