Original Khojo Papers practice question — not from a past board paper.
Answer
Self-pollination preserves the parental characters unchanged and needs no external agent, so pollination is certain and very little pollen is wasted. Against that, it produces no new variation, so the offspring cannot adapt to a changing environment, and continued self-pollination weakens the race over generations.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Cross-pollination has exactly the opposite balance of advantages.
