According to my text book,the genes of identical twins are identical. Does that mean that they are genetically identical too?

If I'm not wrong twins are not completely identical genetically, but they have a small differences, I think in VNTR. Infact these repeteas make the difference between father and son and think between twins.

Identical twins are genetically identical, but there are epigenetic factors which are determined during pregnancy fingerprints is one of them, so they do not have the same fingerprints.
I suppose the differ in many other small things which are not determined directly by the genes.

The mitochondrial DNA may also mutate and change over time, so twins that come from a single zygote can have slightly different mitochondrial genes and traits determined by these genes.
