Differbetween
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.

Why is cross pollination better than self pollination?
Cross pollination is advantageous because it allows for diversity in the species, as the genetic information of different plants are combined. ... Self pollination leads to more uniform progeny, meaning that the species is, for example, less resistant as a whole to disease.
What is the difference between self pollination and cross pollination Class 10?
Self-pollination increases genetic uniformity and decreases genetic variation. Cross-pollination decreases genetic uniformity and increases genetic variation.
Which type of pollination is better?
Answer. cross pollination is better than self pollination as it bring about genetic variation in the offspring. More the genetic variation more the chance of survival in changing environment and adverse condition.
Why is cross pollination bad?
Sometimes it's actually a bad idea to cross-pollinate because the harvest would increase too much. Fruits would stay small and branches may break off. Additionally, trees that bear too many fruits will age and perish within a few years. Over-pollination exhausts the mother plant.
What are 3 types of pollination?
There can be different types of pollination like self-pollination and cross-pollination and these two types also have subcategories, further, we will learn about them in detail. So let's get started with understanding pollination in flowering plants also we will study about types of pollination in plants.
What are the 2 types of pollination?
Pollination takes two forms: self-pollination and cross-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.
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 are the types of self-pollination?
There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm.
What is an example of cross-pollination?
Example. Pumpkins, grapes, grasses, apples, maple trees, daffodils and more. Chasmogamous flowers that facilitate cross-pollination. They develop exposed anthers and stigma.
What are the four agents of pollination?
Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower.
What are the disadvantages of cross pollination?
Disadvantages of cross pollination:
- Pollination may fail due to distance barrier.
- Flowers have to totally depend on the external agencies for pollination.
- More wastage of pollen.
- It may introduce some undesirable characters.
What is the advantage and disadvantage of self-pollination?
Advantages of self-pollination
A very few pollen grain can pollinate the flower. Purity of the race is maintained. Self-pollination avoid wastage of pollen grains. Less chances of failure of pollination.
