Pollination
-
Which one of the following may require pollinators, but is genetically similar to autogamy?In geitonogamy, pollen is transferred to the stigma of another flower of the same plant with the help of a pollinating agent, so it is genetically similar to autogamy.
Xenogamy transfers pollen between different plants; apogamy is reproduction without fertilisation; cleistogamous flowers do not open and self-pollinate. -
