Is it grafted or a seedling?

Believe it's grafted based on what I can see

While they're small like that it's pretty difficult to tell. At least with a grafted plant you can expect it to fruit a lot earlier and that will allow better identification. A grafted plant will usually be a distinct cultivar whereas a seed plant can be a hybrid with varied and 'confused' characteristics. A seed grown plant can take a long time before it produces fruit.

Yep, that's true. I have a Manilla Mango tree that was grown from seed that will take several years to fruit. This one I was hoping that the leaves could be used to identify the kind of Mango since they are quite different looking than the Manilla. My best guess was a Keitt from what I've seen, but was wondering if there were any other identifying features that would provide more insight. Thanks for your info though!

dont think anyone can tell until it fruit.... it can be any varieties.
