Vedclass · Answer

(C) : Unisexuality or dicliny is a condition in which two types of unisexual flowers are present,$i.e.$,staminate (male flower) and pistillate (female flower).In a monoecious plant,unisexual flowers prevent autogamy (self-pollination within the same flower) because the male and female reproductive parts are in different flowers.However,geitonogamy (transfer of pollen from the anther of one flower to the stigma of another flower on the same plant) can still occur in monoecious plants.Therefore,unisexuality prevents autogamy but does not prevent geitonogamy.
