I couldn't agree more with the concern regarding GM Cattle. Why does man constantly think he can improve upon what God already made good?
I'd rather raise a polled dexter than raise a falsely so called traditional dexter that has been genetically modified to no longer have horns. But of course since I don't have to make that choice I'll stick to raising my unadulterated(non-GM) traditional dexters.
I'm happy you posted that link. I saw this gene-editing subject months ago, but didn't have time to post a reply at the time. It's something people should think about before they blindly make decisions to do things that have a lasting impact.
