She notices that although she has had it for two years and it has flowers on it, it does not bear any fruit. All of the flowers are the same and incomplete. She also notices that the plant has enough sunlight and water and bees are regularly in her garden for insect-pollination to occur. Recently, Monica found that a patty pan squash was on her plant. Later that day in her kitchen she also killed a bee from Farmer Brown’s hive which is situated five miles away. Which of the following could be reasons why Monica’s squash took so long to bear fruit? I Self-incompatibility II Hermaphroditism III Patty pan squash is monoecius IV Patty pan squash is dioecius V Protandry VI Protogyny
