Flap, Flep, Flip and Flop are related to each other, but not incestuously.

Among the four are Flap's mother, Flep's brother, Flip's father and Flop's daughter, and the oldest and the youngest are of opposite sex.

One is a different sex from the other three: who?

Flop is the only male, all the others are female.
