Is jumping genetic?

The truth is your genetics do dictate your potential to jump. Muscle fiber type and CNS efficiency are just two examples of traits that will ultimately determine how high you can jump, both of which are nearly impossible to see just by looking at someone. Not everyone can have a 30 inch vertical, much less a 40 or 50.
What determines jumping ability?
Ultimately, the jumping height is determined by the vertical velocity of the centre of gravity at take-off. This velocity depends on the mass of the subject and the linear impulse which is the result of the upward acceleration of the different body segments involved in the jumping action.What makes a person jump high?
Add cross-sectional area (CSA) to your muscles.Lighter, leaner people tend to jump higher because they can create more velocity and more force relative to their body weight, So, you can be as strong as a truck, but if you're also as slow as a truck, that's going to make it hard to leave the ground.
