text: im a twin and i dont get why am i righthanded and my twin sister is lefthanded?   hi!  i'm the mom of identical twins and have read alot on the subject.  1. if you are identical twins then there is a thing called mirror image identical twins.  this means that one is right handed and the other is left handed.  other things that could happen would be if one has a dimple on the right then the other would have a dimple on the left.  it's pretty rare.  2. if you are fraternal twins then you came from two different eggs that were fertilized at the same time.  this means that you are as similiar or disimiliar as any other brothers/sisters out there.  it's not uncommon for families to have children where one is right handed and the other is left handed.  3. the "photo" in the corner is a default shadow.  it will be there unless you add an avatar or picture of your own.  to change it click on "my q&a" (next to the search for questions bar) and select "edit my info" (which is right under the "photo").  hope this helps!
