Pollen transfer occurs in the same plant in self-pollination, whereas the pollen is transferred to a different plant in cross-pollination.
Pollen transfer is limited in self-pollination, whereas in cross-pollination the pollen transfer is in larger amounts.
The offspring is genetically homogenous in self-pollinated flowers, whereas in cross-pollinated flowers the offspring is heterozygous in nature.
Flowers with genetically similar patterns undergo self-pollination, whereas genetically different flowers undergo cross-pollination.
Self-pollinated offspring have almost no or decreased genetic variations, whereas cross-pollinated offspring have increased genetic variations.
Pollinators is not required for self-pollination, whereas pollinators (insects or wind) is required for cross-pollination
Final Answer
Hence, the differences in self-pollination and cross-pollination are listed above.
