What is genetic diversity ?

Explanation

Genetic diversity is the diversity of genes within a species. A single species may show high diversity at the genetic levels over its distributional range. For e.g. Rauwolfia vomitoria, a medical plant growing in the Himalaya ranges shows great genetic variation, which might be in terms of potencyand concentration of the active chemical (resepine extracted from it used in treating high blood pressure) that the plant produces. India has more than 50,000 different strains of rice and 1,000 varieties of mangoes.
Genetic diversity increases with environmental variability and is advantageous for its survival.
