What kind of pear is this? By just the leaf

Hello everyone! I read a lot on these threads, and there is a lot of great information! I’m wondering if the pear aficionados of this forum could help me try to identify this pear by just the leaves since the fruit hasn’t grown enough yet. I can post a picture of the fruit when it’s grown some later.

My dad said he grew it from seed, but I’m not really sure on that. I remember the fruit was small and it was always hard. Kinda like an Asian pear maybe but not much flavor in there.

I’m wondering if it’s a rootstock tree by chance? Or is it really a seedling pear tree? Please help me identify this! Thank you.

Here is a picture of a pear that is starting to form. I don’t know if it helps much. I wonder if it’s still too early to tell.
