@Dakini5d, the genetically modified animals for human organ replacement was my cellular biologist professor's nightmare...so many scientist feel there are too many unknown unknowns playing with systems we don't understand completely....I feel the same way....I've been reading about synthetic human genome project....sounds like one of those scienfiction books I read back in the 90s is coming true...

Thank you <3

If a pig carries human protiens on their liver to avoid transplant rejection...are they human?
