The plants waste a lot of energy on various contrivances required to ensure cross-pollination and there is huge waste of pollen grains in. New varieties can be produced through cross-pollination of two varieties of the same species or two species.

There is more wastage of pollen grains.

. Results in new varieties because cross-pollination can be carried out between two different varieties of the same species or even two species. Disadvantages of cross-pollination There is a high wastage of pollen grains that need to be produced to ensure fertilization occurs. What are the disadvantages of cross pollination of Class 12.

Huge amounts of pollen grains are wasted. One major advantage of self- over cross-pollination is the fact that self-pollination isolates the crop reproductively from its wild progenitorIt 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. The offspring are healthier.

The disadvantage of cross pollination are. Advantages of cross pollination. The seeds develop and germinate properly resulting in healthier plants.

The exchange of dust grains from anthers to the disgrace of a similar blossom is known as self-pollination. The seeds develop and germinate properly and grow into better plants. Immunity of the plants reproduced by cross-pollination increases.

Disadvantages There is more wastage of pollen grains. Advantages and Disadvantages of Self- pollination. In self pollination the wastage of the pollen grains is less than cross Pollination.

New and more useful varieties can be produced through cross-pollination. The plants do not depend on external factors or pollinating agents for pollination. What are the disadvantages of cross pollination of Class 12.

Advantages - Self Pollination confirms that recessive characters are extracted. Offsprings produced are healthier. - Huge amounts of pollen grains are wasted.

What are the two disadvantages of cross pollination. The plants produced through cross-pollination are more resistant to diseases. What are the advantages of self-pollination over cross pollination.

Cross-pollination may introduce some unwanted characters. Disadvantages of cross pollination. Pollen grains have to be produced in abundance to ensure chances of pollination.

Seeds are produced in greater quantities and are more viable. Advantages of Self Pollination. It helps in improving the immunity of offspring against environmental stress and diseases.

- There is a chance of genetic recombination which can lead to elimination of good qualities of the parent. It keeps up with. Disadvantages of Self Pollination.

It eliminates defective traits and is helpful in the production of new varieties. Cross-pollination has the potential to produce healthier plants. There are high chances that the good qualities may get eliminated and unwanted characteristics may get added due to recombination of the genes.

Disadvantages of cross pollination. This results in lot of wastage of pollen. What do you mean by cross pollination write any two disadvantages of cross pollination.

Cross-pollination between two different varieties of the same species or even two species results in new varieties. There is a lot of wastage of the pollen. Self Pollination happens just in the event of sexually open blossoms where the anthers and disgrace mature at the same time.

What are the advantages and disadvantages of cross pollination. Cross-pollination may bring hybrid vigour or heterosis. The disadvantages of Cross-Pollination are given below.

Seeds that are produced are abundant and viable. The children are healthier. It helps in the introduction of new genes into a sequence of species.

There are high chances that the good qualities may get eliminated and unwanted characteristics may get. Pollination may fail due to the distance barrier. It is not always certain as a pollinating agent is always required and it may or may not be available at the suitable time.

Gene variety is there due to the fertilization of genetically varied gametes. The seeds are produced in larger number and are more viable. Results in new varieties because cross-pollination can be carried out between two different varieties of.

The disadvantage of cross pollination are. The other type of pollination is self pollination. This results in lot of wastage of pollen.

2 Cross-pollination is not beneficial from economic point of view. In this process the pollen grain produced in anther falls directly into the stigma of the same flower. Cross-pollination helps to remove the recessive characters by genetic recombination.

What are two disadvantages of cross pollination. Pollen grains have to be produced in abundance to ensure chances of pollination. Similarly which is better self or cross pollination.

In this case purity of race is retained as in the genes there is no diversity. Disadvantages of cross-pollination There is a high wastage of pollen grains that need to be produced to ensure fertilization occurs. 1 Cross-pollination depends on the agents hence uncertainty is always there.

The main advantage of self-pollination is that a plant does not need to have others of its species around to be able to reproduce but the disadvantage is that. It is not always certain as a pollinating agent is always required and it may or may not be available at the suitable time.
