Question

Which of the following conditions will be true if male and female flowers are present in different plants?

• A. Only autogamy is prevented
• B. Only xenogamy is prevented
• C. Both autogamy and geitonogamy is prevented
• D. Both geitonogamy and xenogamy is prevented

Answer 1

The correct option is C

Both autogamy and geitonogamy is prevented

Pollination that occurs within the same flower is known as autogamy (or self pollination) while pollination that occurs between two flowers of the same plant is known as geitonogamy. If male and female flowers are present in different plants, then both autogamy and geitonogamy can be prevented. Hence, self pollination can be prevented by production of unisexual flowers.
