Question

Genetic diversity in agricultural crops is threatened by

• A. Extensive use of fertilisers
• B. Intensive use of biopesticides
• C. Introduction of high-yielding varieties
• D. Extensive intercropping

Answer 1

The correct option is C

Introduction of high-yielding varieties

Genetic diversity in agricultural crops is the most important step in biodiversity conservation. So the use of fertilisers and pesticides does not have an impact on diversity, but the introduction of high-yielding varieties causes a decline in genetic diversity of crops.
