Question

Advantages and disadvantages of cross pollination

Answer 1

Advantages of cross pollination:

1 Progeny shows enhanced vigor.
2 Offsprings are more viable and resistant.
3 There is a possibility to get new desirable characters.
4 Yield of crop can be maintained.
5 It helps in evolution.
6 Undesirable characters of the plant can be eliminated.

Disadvantages of cross pollination:

1 Pollination may fail due to distance barrier.
2 Flowers have to totally depend on the external agencies for pollination.
3 More wastage of pollen.
4 It may introduce some undesirable characters.

Answer 2

Advantages of cross-pollination:

• The offspring are healthier.
• The seeds are produced in greater quantities and are more viable.
• The seeds properly develop and germinate and form into healthier plants. If we do cross-pollination between entirely different two varieties, it will form a new species.

Disadvantages of cross-pollination:

• In this pollination each and every time a pollinating agent is required, it is not affordable for every time.
• To ensure the chances of pollination, pollen grains must be produced in abundance. This leads to a lot of pollen wastage.
• It is inexpensive for plants which produce large, perfumed and nectar flowers to attract insects.
