Assertion : Although geitonogamy is functionally crosspollination involving a pollinating agent, genetically it is similar to autogamy.
Reason : In geitonogamy, pollen grains from the anthers of one flower are transferred to the sigma of another flower borne on the same plant.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

a

Explanation

Geitonogamy is a type of pollination in which pollen grains of one flower are transferred to the stigma of another flower belonging to either the same plant or genetically similar plant. It usually occurs in plants which show monoecious condition (unisexual male and female flowers are borne on the same plant). Thus, geitongamy is functionally cross pollination as it involves the pollinating agent to carry out pollination, but genetically it is similar to autogamy (self-pollination) since the pollen grains come from the genetically same plant.
