Question

India has 1000 different varieties of mangoes. This is an example of

• A. species diversity
• B. genetic diversity
• C. ecological diversity
• D. species richness

Answer 1

The correct option is B genetic diversity

1000 different varieties of mangoes found in India arise due to differences in the genetic composition between each variety and is an example of genetic diversity.

Genetic diversity refers to the variations observed at the genetic level, i.e., in the genetic composition of organisms belonging to the same species.

Species diversity refers to the variety of species in a region and is determined by its species richness (number of species present per unit area of a region). The huge variety of amphibian species found in the Western Ghats when compared to the Eastern Ghats indicates high species diversity in this region.

Ecological diversity is seen at the ecosystem level. A country like India which has a vast array of ecosystems such as rain forests in the North Eastern region, alpine meadows in Himachal Pradesh, Uttarakhand or Jammu Kashmir, deserts in Rajasthan, etc is said to be highly ecologically diverse.
