Is Jackfruit tree self-pollinating?

[Siyu98]

Hi，
I have some little jackfruit trees in pots and, according to the seller, they should be fruiting in 4-5 years. However, I cannot move them outside because of freezing winters. Can I keep growing them in pots? And are jackfruit trees self-pollinating?

Jakfruit trees are self pollinating.

My Gold Nugget jak is 10" + in diameter at the base of the trunk, I guess it is 20' tall and probably weighs over a ton.

I don't know if mine is typical jak but they for sure have to be pretty sturdy to support such BIG fruit.
