>>10983034>crispr some shrimp eyes onto people?CRISPR doesnt quite work like that. You need to start from the egg to have a decent shot at full genetic transmission.
If you start from the egg, and manage to somehow fenangle the right set of genes to code for shrimp eye and silence the human eye genes, however, it is indeed possible in principle.
Why you waste so much effort accomplishing such an affront to god is a question I can't answer.
