every somatic cell of the trillions that make up a grown human has the potential to grow into a fully-formed human. And so, if a fertilized egg has a soul worthy of being granted full human rights, then so does every somatic cell.
This is easy to counter: As long as you don't know what a "soul" is and by "whom" or "what" it is given you can't know what "his" selection process and criteria are to "give" souls to entities. "He/It" might even say simply "Sorry, no souls for cloned humans!".
Your arguments are coming from a purely mechanistic view of the world, which a believer in souls must not necessarily share - - - as you yourself apparently do not share his belief in a "soul" and therefore put it in Apostrophs. Mixing this up, pretending what you don't believe in and saying "If there were souls...", and then trying to falsify it by now arguing mechanistically "....then biology/physics says..." does not work.
