Answer 2

Answer:

Explanation:

Pollination is the transfer of pollen grains from the anther of one flower to the stigma of the same or another flower. It is said to be the first process of sexual fertilization in flowering plants. Pollen grains contain the male gamete and are present in the anthers of the flower.

Advantages of pollination

• In self- pollination, there is no diversity in the genes and therefore the purity of the race is maintained.

• The plants do not depend on external factors for pollination and even smaller quantities of pollen grains produce have a good success rate in getting pollinated.

• Self- pollination ensures that recessive characters are eliminated.

Disadvantages of  pollination

• Since there is no mixing up of genes, there are no new characters or features that are introduced into the lineage of the offsprings.

• Self- pollination is said to reduce the vigor and vitality of the race as there are no new features introduced.

• Without new characters introduced, the resultant offsprings’ immunity to diseases reduces.
