Text Solution

Verified by Experts
The correct answer is:
A

P1 is autogamy. P2 is geitonogamy, P3 xenogamy.
P3 (cross-species pollination) would likely result in more genetic variation than P2 (cross-pollination within the same species). Maize is monoecious thus it typically involves crosspollination (P2) flowers of the same plant or P3 between plants of the same species. Papayas are generally dioecious (separate male and female plants), so cross-pollination (P2) is possible, but cross-species pollination (P3) is not a typical occurrence in papayas.
