I was told by a Biotech professor (who came in our college for a guest lecture) that Bio Technology has now become so advanced that if we want to make an identical twin (or Genetical DNA Twin) of a person then we can now be able to it using his DNA. I am a Mathematics Student so I don't know much about it. I just attended the lecture because I found it interesting. I am sorry, I know I should have asked this very simple question in Quora but, I wanted a precise answer which could be believed. So I asked here, where I will get answers only from the very experts. I apologize again Thank You So Much in advance 😊
Edit 1 :- I am satisfied with @Remi.b 's answer, @Bryan 's explanation and @anongoodnurse ' references. I should also have mentioned genetical DNA Clone in the place of identical twin. Now I've added.
