Advantages and disadvantages of self- fertilization

Advantages of self-fertilization:

1. it increases the chances of fertilization and formation of new organism.
2. only one parent is required, and that beneficial qualities are more likely to be passed on to the offspring since all offspring are genetically identical to the parent.

Disadvantage of self- fertilization:

1. it reduces genetic variability, so the organism will be less adapted to changes in the environment.
2. It may transfer diseases to the offspring
3. Cross fertilization: is the union of gametes from the different individual or flower of the same species. This brings in genetic mixing and genetic variability which increase the hybrid vigour.
