But genetics doesn’t mean that every family member will have identical hands.

Human anatomy naturally varies.

Even identical twins can develop subtle physical differences over time.

Joint flexibility and muscular strength are different characteristics.

Someone can have flexible joints and strong muscles.

Someone else can have relatively limited flexibility but still have considerable hand strength.

What matters functionally is how the joints, muscles, tendons, ligaments, and nervous system work together.
