Vedclass · Answer

(A) The introduction of high-yielding varieties (HYVs) has led to a significant reduction in genetic diversity.

This practice creates a monoculture,making crops more susceptible to diseases and pests,and results in the loss of valuable genetic traits present in traditional varieties.
