When j=k=1 then the race condition is occurs that means both output wants to become high. Hence there is toggle condition is occurs.

Toggle means the output is not fixed. First Q is high next complement of Q becomes high. So output always changes from Q HIGH to complement Q HIGH.

When j=1 and k=1, with each passing clock pulse the output Q changes from 0 to 1 and 1 to 0. That's why its called a toggle state.

In J-K flip-flop output is fed back to the input. Therefore the change in the output results in changes in the input. Due to this in the positive half of the clock pulse if both J and K are high then output toggle continuously. This is called race around condition.
