Explanation
Solution
Variations are the dissimilarities, which help in distinguishing one member of the species from other. Environmental variations are occurred due to envirobmental changes. They are also known as acquired variations. These are not inherited to next generation. So they are temporary in nature. Discontinuous variations sudden changes, which are discontinuous in nature. These are known as mutations. These are inherited variations. Hereditary variations are inherited to the offspring because they occurs in genetic material.
