Identical Twins' Genes Are Not Identical

  Also with monozygotic twins the pre birth environment is not identical either. Given both these effects it is amazing how similar many monozygotic twins are to each other.

    I've seen quite a few examples of dizygotic twins that are amazingly similar. E.g. these two https://en.wikipedia.org/wiki/Mary-Kate_and_Ashley_Olsen https://en.wikipedia.org/wiki/Mary-Kate_and_Ashley_Olsen seem quite similar to my untrained eye.

      Yes they can be. I have always amazed at those families where each of the children is like a clone.

  This is a fascinating finding. Does this also imply that an individual might have number-copy variants across his/her own body?

    Yes. Your own cells are not identical genetically.
