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 a different gender from the others.
I began by substituting letters for the funny confusing names.
Flap=A
Flep=B
Flip=C
Flop=D
We have A's mother, B's brother, C's father and D's daughter.
Because three of them are the same gender, either A's mother = D's daughter or B's brother = C's father.
If A's mother = D's daughter, then we violate the rule that the youngest and oldest are of opposite gender.
So B's brother = C's father.
B (female) -------------> D (male)

C (female)

A (female)
Putting the original names back:
Flap, the youngest, is Flip's daughter.
Flip, the second youngest, is Flap's mother and Flop's daughter.
Flop, the oldest, is Flip's father and Flep's brother.
Flep, the second oldest, is Flop's sister.
