what is a sticky gene

hi excuse me what is a sticky gene ? my teacher tell me it isnt a sticky end or a transposon
i search on some genetics books but i cant find anything normally they talk about sticky ends and transposons so i dont know the same on internet please help me


i have already ask him about it i ask if she was talking about sticky ends or , transposons even translocation but she tell that it wasnt that it has to do with bad luck families and no disjunction
they cause some sickness like
down
turner
Klinefelter
it is a numéric alteration of the cromosomes

No idea, doesn't ring a bell.
