Short, bent legs (dwarfism)
Every short-legged Munchkin has the UGDH gene that makes the long leg bones grow short, thick and a little bent. It can walk, run and play, but jumps less high, and washing itself is harder. How bent the legs are differs from cat to cat. A kitten that gets the gene from both parents does not survive; that is why a short-legged Munchkin always has one copy.
How it is found: It shows from birth; X-rays show how short and bent the bones are. A DNA test also exists.
