why does a p-channel JFET differ from an n-channel JFET?

hi...

why does a p-channel JFET differ from an n-channel JFET?

what is the difference between them?

The p-channel has all the voltages and currents in the other direction.
The p-channel is complementary to the n-channel.

The positives ('p') and negatives ('n') are swapped in the substrate.
