Which one of the following may require pollinators, but is genetically similar to autogamy?
Correct answer: C. Geitonogamy
- A. Apogamy
- B. Cleistogamy
- C. Geitonogamy
- D. Xenogamy
Explanation
Geitonogamy involves the transfer of pollen from one flower of a plant to the stigma of another flower of the same plant. As the pollen has to move from one flower to another flower, it requires a pollinating agent. Yet it is genetically similar to autogamy, as both the flowers of the plant, share the same genotype of the plant. A. A type of reproduction occurs in some ferns, in which sporophyte develops from gametophyte without fusion of gametes. B. Self-fertilization that occurs within a permanently closed flower. D. Fertilization between genetically different flowers on different plants.

The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
