A mango plant grown by grafting is better than seed.
Step-by-step explanation:
A mango plant grown by grafting is better than seed because when a seed is grown in to plant it necessarily may not contain the same characteristics or phenotypes of the parent plant. The phenotype of the new plant depends upon the cross-breeding of the male and female zygotes.
Grafting of plants will grow into a new plant with exactly the same phenotype of characters of the parent plant, like the fruit quality with color, flesh or pulp quality, number of fruits, time of fruiting, etc.
