Ja Morant's 4-year-old daughter showed the apple doesn't fall far from the tree ... the NBA superstar's baby, Kaari, showed off her hoops skills in a 1-on-1 matchup against her mom, Kadre -- and it's adorable!

Kadre shared the video on social media, despite being scored on (sometimes the offense is just that good!), showing Kaari driving to the left, with handles that'd make dad proud, before knocking down the lefty layup, as mom could just stand there and watch.

Kaari was clearly impressed with her work on the court ... and she let everyone know about it, yelling, "You see the guns?! You see the guns?!" as she flexed.

Kadre -- who gave birth to Kaari in 2019 -- captioned the video with a question ... how does her daughter already have A+ trash talk?!

Ja's sister, high school hooper Niya, took the credit, saying her niece got it from her.

"Deflee got it from her tt," Niya said, "but whateva 🙄😂😂😂😂."

It seems hooping runs in the family (and some trash-talking, too) ... and thankfully for NBA fans, Morant is gearing up to return later this month when his 25-game suspension ends.

Ja will be eligible on Dec. 19, and the 5-14 Grizzlies desperately need him.
