  Hi,
  Does somebody know how you can determine wether variegation is caused by transposon insertion or transposon excision?
  It would be of great help
  greetings,
  Sam

  I would guess rather insertion. But theoretically, if you had embryo with inserted transposon and it got excised in part of cells, you could get it too… (but kind of reversed)

  Insertion, transposable elements can regulate genes epigenetically, when inserted within or very close to them… Much example can be found on RNAi..

  My book (Introduction to genetic analysis, Griffiths et al,9E) says both can be the cause, and exactly in the way Jackbean says.
  But our professor gave a list with possible questions for my genetics exam and one of the questions is:
  "how can you determine wether a variegation is caused by a insertion or rather an excision"
  I think I know sort of what she means but I can’t put it into words
