2 Peter and other biblical writings

2 Peter has eleven references to the Old Testament, besides the mention of the Pauline letters.  There is a reference to the gospel tradition also, mainly in the Transfiguration of Jesus and in the promise of the Second Coming.  2 Peter shares a number of passages with the Epistle of Jude also.  Scholarly consensus is that Jude was the source for these similar passages with 2 Peter.  Can you tell who copied who?
