Vedclass · Answer

(D) In monoecious plants like castor and maize,both male and female flowers are present on the same individual plant. $1$. Autogamy (self-pollination within the same flower) is prevented because the flowers are unisexual. $2$. Geitonogamy (pollination between two different flowers on the same plant) is not prevented because both male and female flowers are on the same plant. Therefore,the correct statement is that geitonogamy is not prevented.
