If you mixed genes of a human and a horse in a lab, is it possible to make a centaur? And are narwhals part unicorn?

Question: If you mixed genes of a human and a horse in a lab, is it possible to make a centaur? And are narwhals part unicorn? What would happen if you mixed narwhal DNA with horse DNA, would you create a unicorn!?

  I think this question is my favourite so far because it made me laugh and I hope you are not asking this in seriousness as the answer is no to all of them, if you are then I recommend you pay more attention to genetics and I can recomend a good book!
  
  If not then I am pretty sure someone else has asked if a narwhal is a unicorn so maybe they already have been mixed 😉
