I noticed that when I take a bunch of horses and "inject" DNA via the CRISPR lab, it doesn't create a perfect copy. (I edit them one at a time) Some of the horses can look different and act differently. If it "changes" helix 19/18, it can even slow the speed of the horse, sometimes making the horse completely immovable.

Is this a feature of the game, or am I doing things wrong/any way to bypass it?
