If you wish to promote the transfer of genetically different types of pollen grains to the stigma, which of the following will help you in this regard? Autogamy Geitonogamy Xenogamy Cleistogamy
Answers
Answer:
Correct option is
A
Xenogamy
• Xenogamy is the cross pollination between the flowers of different plants. It produces hererozygosity because two genetically different parents are involved.
• Geitonogamy is a type of self pollination in which pollen are transferred from the anther of one flower to the stigma of another flower of the same plant.
• Chasmogamy is the condition in which bisexual flowers have exposed anthers and stigma. Both self pollination and cross pollination can occur in these flowers.
• Autogamy is a type of self pollination in which pollen are transferred from the anther to the stigma of the same flower.
Thus, it's xenogamy that can bring genetically different pollen grains to the stigma of a plant. So, the correct answer is A.
Answer:
Xenogamy
Explanation:
In xenogamy, the egg of a flower of a plant is fertilized by the pollen of a flower of a Genetically different plant.
Autogamy also known as self pollination, here the pollen of a flower fertilizes the egg of that same flower.
In Geitonogamy, pollen from a flower fertilizes the egg of another flower from the same plant.
In Cleistogamy, flowers are usually closed and so the pollination occurs there is autogamy or self pollination.
