Self-pollinated flowers have small, light weighted and fewer numbers of seeds. Continuous self-pollination results in the production of weaker progeny. there are no chances of the production of new species and varieties of plants. The chances of evolution is also reduced.

What are the disadvantages 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 advantages and disadvantages of self and cross pollination?

It is the basic form of pollination because it only involves one flower. Self-pollination

• The purity of the race is maintained.
• There is no wastage of pollen grains.
• Self-pollination ensures that recessive characters are eliminated.
• The plants do not depend on external factors or pollinating agents for pollination.

What are the five advantages of self-pollination?

The advantages of self-pollination are as follows:

• Much surer in bisexual flowers where stamens and carpels mature simultaneously.
• Indefinite preservation of parental characters.
• No wastage of pollen grains.
• Flowers are not required to be showy and large.
• Nectar and scent are not required to be produced by flowers.

What are the advantages of pollination?

With adequate pollination, wildflowers: Reproduce and produce enough seeds for dispersal and propagation. Maintain genetic diversity within a population. Develop adequate fruits to entice seed dispersers.

Which one is the advantage of self-pollination?

During self-pollination, the pollen grains are not transmitted from one flower to another. As a result, there is less wastage of pollen. Also, self-pollinating plants do not depend on external carriers. They also cannot make changes in their characters and so the features of a species can be maintained with purity.

What are the advantages of self-pollination over cross pollination?

One major advantage of self- over cross-pollination is the fact that self-pollination isolates the crop reproductively from its wild progenitor. It enables the farmer to grow a desired genotype in the same area in which the wild relatives abound without endangering the identity of the cultivar by genetic swamping.

What are two advantages of cross pollination?

The Advantages Of Cross-pollination are as follows:

• Offsprings produced are healthier.
• New varieties can be produced through cross-pollination of two varieties of the same species or two species.
• Seeds that are produced are abundant and viable.
