The Twist

Despite the fact that the dinosaurs bred for Jurassic Park have been consciously tinkered with to make sure that they're all female, it turns out that the scientists messed up and accidentally used the genetic material of some frogs that can change their gender when population imbalance requires it.

Those scientists were never all that clever. Naturally, some of the dinosaurs become male and they all mate, leading to offspring, because life... finds a way.

The Reveal

There's a very cheeky hint at this revelation early on when Doctors Grant, Sattler and Malcom join John Hammond and Donald Gennaro on the helicopter heading to Isla Nubar.

As the chopper makes it descent, everyone buckles up, only for Grant to find he has two female buckles. Undeterred, he "finds a way" and simply ties them together, offering a nice little hint of the dinosaur gender twist in the process.
