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 (slash-and-burn agriculture) often results in the loss of local landraces and biodiversity in forest ecosystems. $3$. The adoption of genetically uniform high-yielding crop varieties (monoculture) replaces traditional,diverse landraces,leading to a significant reduction in the genetic pool of crops. Therefore,all the mentioned factors contribute to genetic erosion.
