What is the difference between Allogamy and Xenogamy?

The main difference between allogamy and xenogamy is that allogamy is the deposition of pollen grains from the anther of the one flower on the stigma of another flower, either in the same plant or a in a different plant of the same species whereas xenogamy is the deposition of pollen grains from the anther of one ...

What is the difference between Autogamy and Geitonogamy?

Autogamy refers to the transfer of pollen grains from the anther to the stigma of the same flower, whereas geitonogamy refers to the transfer of pollen grains from the anther to the stigma of another flower of the same plant.

What is difference between cross pollination and self pollination?

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

What is Autogamy and Allogamy discuss one feature of them?

Why is complete Autogamy rare?

Complete autogamy is rare in chasmogamous flower. Perfect synchronization between pollen release and stigma receptivity is required in such flowers to allow self-pollination. Cleistogamous Flower: When a flower does not open at all and thus does not expose its anthers and stigma, it is called cleistogamous flower.

What is the disadvantage of self-pollination?

The 3 disadvantages of self-pollination are as follows: May lead to the weakening of variety or the species due to continued self-pollination, thereby affecting the quality of offspring. Defective or weaker characters of the variety or breed cannot be eliminated.

What is called self-pollination?

Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms).
