Question

Type of pollination that brings genetically different types of pollen grains to the stigma of a plant is

• A. Xenogamy
• B. Geitonogamy
• C. Chasmogamy
• D. Autogamy

Answer 1

The 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.
