Here genetics play a role but it’s not determined by the single although it involves the multiple gene with complete variations

Handedness is largely determined by genetics and brain asymmetry, and it’s established early in development.The left hemisphere of the brain controls the right hand (and vice versa), and in most people even many left-handers the left hemisphere is dominant for language and fine motor skills, which influences handedness.

Handedness is primarily decided by the asymmetrical activity of the brain’s motor areas, especially the motor cortex. It’s influenced by a combination of genetics, prenatal environment, and brain lateralization.

Yeah. Otherwise in general, practice can makes a person writing with both the hands.

I am a left-handed person.
I mostly hear taunts because of my left handedness.

Is it right…like don’t eat with your left hand etc.??
