Autogamy is defined as the type of self-pollination in which pollen grain fall on the stigma of same flower.
Allogamy is also known as cross-pollination. In allogamy pollen grain from another flower falls on stigma of a flower growing on another plant of same species.

Welcome Students,

◆ Difference between autogamy and allogamy -

  1. Autogamy is type of self pollination and allogamy is type of cross pollination.
  2. In autogamy, egg cell fuses with sperm cell of same plant while in allogamy egg cell fuses with stem cell of different plant.
  3. Autogamy is of only one type but allogamy is further classified as xenogamy & geitonogamy.
