Answer:
The problems/ disadvantages of pollination are as follows:
CROSS POLLINATION
- There is a high wastage of pollen grains that need to be produced to ensure fertilization occurs.
- There are high chances that the good qualities may get eliminated and unwanted characteristics may get added due to recombination of the genes.
SELF POLLINATION
- Without new characters introduced, the resultant offsprings’ immunity to diseases reduces.
- 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.
