didnt use kind of punnet square....just some good old fashioned common sense...
Breed a visual animal to a visual animal and there is no way you can get a nonvisual offspring...simply for the fact that both every offspring will get atleast one copy of said genes
there would be 25% normals...
If your statement above were true, then the flipside would also be true..... Normal looking het x normal looking het couldn't producing anything except normals... We all know that isn't true.
