I didn't really know how to do translocation so this is what I did.
Mutations can affect us humans in good ways. For example we could develop to survive harsher temperatures and underwater by growing a thicker skin coat and gills. But there are also bad mutations. For example you showed us a cat that was born with 2 heads and couldn't survive because the heart couldn't support both heads. Also, it can be bad because it can cause lethal diseases. It also benefits because it might make us do things that we never thought of doing.
