Question

The allogamy is best favoured by:

• A. Homogamy
• B. Cleistogamy
• C. Dicliny
• D. All of the above

Answer 1

The correct option is C Dicliny

Allogamy also known as cross fertilization is the transfer of pollen grains from anthers to stigma of a flower borne on different plant. It is best favoured by dicliny where the flowers are unisexual which means the stamens and pistils are borne on separate flowers.

Homogamy is a condition of having only one type of flower, one which produces both male and female parts on the same flower.

Cleistogamyis a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and beans, this behavior is most widespread in the grass family.

Thus, the correct answer is option (C).
