Vedclass · Answer

(D) Genetic erosion refers to the loss of genetic diversity within a species or population. $1$. Deforestation leads to the destruction of natural habitats,causing the loss of wild relatives of crops and diverse plant species. $2$. Shifting cultivation often involves clearing large areas of land,which can lead to the loss of local landraces and genetic variability. $3$. The adoption of genetically uniform high-yielding varieties (HYVs) in modern agriculture replaces traditional,diverse landraces,leading to a significant reduction in the genetic pool of crops. Therefore,all the mentioned factors contribute to genetic erosion.
