Question

Intraspecific incompatibility can over come by

• A. Wetting of anthers
• B. Mixed pollination
• C. Intraovarian fertilization
• D. Intraspecific competition

Answer 1

The correct option is B Mixed pollination

B. Mixed pollination

Reason: Intraspecific incompatibility or self incompatibility means the incompatibility between the two organism of same species. Sometimes pollen grains are incompatible to the stigma of a same species. As a result, germination get arrested. In Mixed pollination technique, a mixture of of chemically or irradiatedly treated compatible Pollen and live incompatible pollen is used to pollinate the plant. The stigma is camouflaged from recognising the incompatible pollen through some proteins secreted by modified compatible pollen.
