Question

Transfer of new genes into wild species through natural out-crossing leads to:

• A. Gene revolution
• B. Gene pollution
• C. Biopiracy
• D. Green revolution

Hint:

Gene pollution threatens the genetic integrity of wild plant populations.

Answer 1

The Correct Option is B

Step 1: Understand the question.
We must name what happens when new genes move into wild species through natural cross-pollination (out-crossing).

Step 2: Picture the situation.
A genetically modified crop carries new genes. Pollen from this crop can drift to nearby wild relatives and fertilise them.

Step 3: See the result.
The wild plants now carry genes they never had before. This is an unwanted spread of altered genes into the wild gene pool.

Step 4: Rule out the wrong terms.
Gene revolution and green revolution describe farming progress, not gene escape. Biopiracy means taking biological resources without permission. None of these fit.

Step 5: Name the correct term.
The unwanted flow of engineered genes into wild species is called gene pollution or genetic contamination.

Step 6: Final answer.
The right term here is gene pollution.
\[ \boxed{\text{Gene pollution}} \]
