Why does nature prefer cross pollination?

Answer 1

Cross Pollination can give rise to new breeds or new varieties of plant. Another disadvantage of self pollination is that, if there was an unrequired character for the plant, it will be carried over to the new and younger generations. This all what i know. Hope it helped you.

Answer 2

In Cross pollination the pollen grain of anther of a flower of one plant land on the stigma of a flower of another plant of the same species.It is considered superior to self pollination because-

1) The seeds produced contain another source of genetic material which may contain genes that are advantageous for the survival of the seedling.

2) It is a source of variation in offspring because of intermixing of genetic material and process of crossing over during meiosis in the gametes.

3) The seeds are more viable and healthier with a better germinating capacity.

4) It gives more scope for evolution of a new species of plants hence adding to biodiversity.

Answer 3

Cross pollination is advantageous because it allows for diversity in the species, as the genetic information of different plants are combined.Other than that,Cross pollination introduces genetic re-combinations and hence variations in the progeny and is stronger.Therefore,the plants produced through cross pollination are more resistant to diseases.

Answer 4

To promote new genetic combinations for evolution and better adaptability.

Answer 5

because they need the pollen another plant of the same species to produce fruit, etc. and mostly bees do it but sometimes you have to do it yourself

Answer 6

That will help maintain a greater variety of plants.
