Answer
The two events involved in the sexual reproduction of a flowering plant is Pollination and Fertilisation.
(i) Pollination is the transfer of pollen from the stamen to the stigma. Different types of pollination are self-pollination and cross-pollination.
· The transfer of pollen from the stamen to the stigma of the same flower is called self-pollination.
· The transfer of pollen from the stamen of one flower to the stigma of another is called cross-pollination.
(ii) Advantage of self- pollination - In self- pollination, there is no diversity in the genes and therefore the purity of the race is maintained. Disadvantage of self- 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.
