A clone sounds wrong; I would say something like "Clones" or "Cloning" to introduce the subject. Also, the second part of the title should be called "A visual commentary on genetic engineering." Finally, a title is never in two sentences, like you have written. I would probably write the title as, "Clones – a visual commentary on genetic engineering", or with the dash replaced by a colon (:).
As for the English in your post, it is quite good, but one must end questions with a questions mark, no? Also, it would be better style to enclose your suggested titles in inverted commas ("") but perhaps by this point I am nitpicking.
