Which of the following contravince promotes Autogamy, Gietonogamy and Xenogamy ?

Bisexuality
B
Unisexuality
C
Dioecy
D
Monociosim
Answer
Bisexuality
Explanation
Solution
Autogamy requires both male and female parts in the same flower. Bisexuality (presence of both male and female reproductive organs in the same flower) is the essential condition for autogamy. A plant with bisexual flowers can also undergo geitonogamy (pollination between flowers on the same plant) if it has multiple flowers, and xenogamy (pollination between flowers on different plants) by exchanging pollen with other plants. Therefore, bisexuality is the contrivance that promotes (makes possible) all three types of pollination.
