Genetic diversity
- At the genetic level, a single species may show high diversity over its distributional range.
- Example 1: Rauwolfia vomitoria (a medicinal plant) growing in different Himalayan ranges show genetic variation in terms of potency and concentration of the active chemical (reserpine) produced by the plant.
Example 2: In India, more than 50,000 genetically different strains of rice are found.
Example 3: In India, more than 1,000 varieties of mango are found.
