Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Gene Pollution: Gene pollution, also known as genetic pollution, occurs when genes from a genetically modified organism are transferred to a non-genetically modified organism (especially a related wild species). This transfer often occurs through pollen, as it can travel to nearby related species, causing a change in the genetic structure of that species. It is termed ‘pollution’ because the spread of genes is unregulated, and can cause unexpected effects.
Gene Transfer: Gene transfer, while related to the movement of genes, does not specify the negative implications of the escape. It is more of a general term for genetic material transfer, and this might be in a controlled environment.
DNA Contamination: DNA contamination refers to the introduction of unwanted DNA into a sample or system which is not necessarily from pollen. This can happen because of laboratory practices, or accidental contamination.
Toxicity Transfer: Toxicity transfer refers to the transfer of toxic substances, and this is usually not related to transfer of genetic material.
