1)What is Cross Pollination?
2What are the Advantages and Disadvantages of Cross Pollination?​

Answer 1

Answer:

1) Cross-pollination is the process of applying pollen from one flower to the pistils of another flower.

2)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.

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.

Answer 2

ANSWER:—

1) 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. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.

2) The Advantages Of Cross-pollination are as follows:—

• Reproduce and produce enough seeds for dispersal and propagation.
• Maintain genetic diversity within a population.
• Develop adequate fruits to entice seed dispersers.

Disadvantages of cross pollination

• The uncertainty will always be there as the cross-pollination is dependent on the agents.
• There is a huge loss of energy and waste of pollen grains during the cross-pollination.
